Description
ULTRA HIGH PRESSURE PUMPS
Field of the invention The present invention is an improvement of the patented invention "Multi-chambers and Motor-pumps to generate Ultra high pressure", corresponding to Chilean patent application No. 2331-2006, of the same inventor; and it can have application in several fields or can have different uses: food subject to ultra high pressure, cutting of metal plates by liquid jets, ultra high pressure sintering, research of new materials, etc.
Description of the state of the art The previous state of the art is determined by the state of development wherein multiple chambers are disposed in series one inside the other, or are concentric, there is a hydraulic motor-pump inside each chamber and the pressure increasing technique is based on a new way of achieving ultra high pressure, by repeating the pumping operation, so that the liquid pumped into any chamber and entering the motor-pump inside said chamber is divided in two, one portion entering the "motor cylinder" and the other entering the "pump" cylinder for, on the one hand, by subsequently reducing the pressure inside the "motor"
cylinder, delivering power to the other portion of the liquid which therefore increases even more its pressure and is pumped to the next chamber disposed further inside the multi-chamber arrangement where it is recursively divided again, thus increasing the pressure of the liquid even more. In this prior art technology there is however a simple chamber for every motor-pump, as in the mentioned invention "Multichamber and motor-pumps to generate ultra high pressure", but it has not been recognized that it is more efficient when double walled chambers are used, or when chambers with triple walls or more are used for each motor-pump, which is the same to say that each motor-pump has several chambers for each motor-pump.
Indeed, it is known that when in any chamber subject to a higher internal pressure than the external one the thickness of the walls is reduced, the compression stress gradient in the wall is also reduced. Under this condition, to achieve the same final ultra high-pressure within the innermost chamber of a multi-chamber device with motor-pumps like the one of application 2331-2006, a larger number of these chambers of lower wall thickness would be required, the sum of thicknesses of the chamber's walls being however less than the sum of thicknesses of the chamber walls of the equivalent apparatus like the one of which has chamber walls of "normal" thickness. If no further modifications are effected, the resulting device will also have a larger number of motor-pumps, which is not efficient and it is also more expensive, hence the need not to increase the number of motor-pumps, or even decrease it, while maintaining the advantages offered by the reduction of the thickness of the walls of the chambers.
Summary of the invention In an aspect, the present invention seeks to provide a multi-chamber pressure-increasing device, to produce ultra-high pressure within a defined volume through an iterative process.
The multi-chamber pressure-increasing device includes a plurality of chambers arranged in series, one within the other, from an outermost, first chamber until an innermost, last chamber, in which objects or samples can be installed in said last chamber to be subjected to said ultra-high pressure, and an external pump connected to the first chamber to fill said first chamber with pressurized fluid through an outgoing fluid line of the external pump.
The multi-chamber pressure-increasing device also includes a hydraulic motor-pump mounted in each chamber, except for the innermost chamber, wherein each hydraulic motor-pump consists of two cylinder-piston assemblies or two bellows that form the motor part and pump part of the hydraulic motor-pump, wherein the motor part is operatively connected to the pump part so that pressurized fluid is admitted simultaneously into both parts or is discharged simultaneously from within both parts and wherein the motor part drives the pump part for pumping pressurized fluid from within the same chamber in which it is mounted, through a respective outgoing fluid pumping line and at a higher pressure than the pressure in the chamber in which it is mounted, to the subsequent, more internal chamber. At least one of the chambers is composed of a set of sub-chambers arranged in series one inside the other, each set of sub-chambers having an innermost sub-chamber and an outermost sub-chamber, wherein the hydraulic motor-pumps are mounted in the innermost sub-chamber of each set and the rest of the sub-chambers have a pressurized fluid admission valve connected to the outgoing fluid pumping line coming from hydraulic motor-pump mounted in the preceding chamber or, in the case of the first chamber, to the fluid line coming from the external pump, wherein each valve is actable to close at a predetermined fluid pressure which is incremental from the innermost sub-chamber to the outermost sub-chamber.
In another aspect, the wall of said at least one chamber composed of a set of sub-chambers is a multiple wall with space in-between the walls that define said sub-chambers.
Description of the drawings Figure 1 shows an example of embodiment of the present invention, of a multi-chamber pressure- increasing device, to produce ultra-high pressure within a predetermined volume in the innermost part of the device through an iterative process.
Figure 2 is a close-up of detail "A" of Figure 1 showing pressurized fluid admission valves for each space in between the multiwalls of the first chamber and for the motor part of the hydraulic motor-pump of the first chamber.

Summary of the invention In an aspect, the present invention seeks to provide a multi-chamber pressure-increasing device, to produce ultra-high pressure within a defined volume through an iterative process.
The multi-chamber pressure-increasing device includes a plurality of chambers arranged in series, one within the other, from an outermost, first chamber until an innermost, last chamber, in which objects or samples can be installed in said last chamber to be subjected to said ultra-high pressure, and an external pump connected to the first chamber to fill said first chamber with pressurized fluid through an outgoing fluid line of the external pump.
The multi-chamber pressure-increasing device also includes a hydraulic motor-pump mounted in each chamber, except for the innermost chamber, wherein each hydraulic motor-pump consists of two cylinder-piston assemblies or two bellows that form the motor part and pump part of the hydraulic motor-pump, wherein the motor part is operatively connected to the pump part so that pressurized fluid is admitted simultaneously into both parts or is discharged simultaneously from within both parts and wherein the motor part drives the pump part for pumping pressurized fluid from within the same chamber in which it is mounted, through a respective outgoing fluid pumping line and at a higher pressure than the pressure in the chamber in which it is mounted, to the subsequent, more internal chamber. At least one of the chambers is composed of a set of sub-chambers arranged in series one inside the other, each set of sub-chambers having an innermost sub-chamber and an outermost sub-chamber, wherein the hydraulic motor-pumps are mounted in the innermost sub-chamber of each set and the rest of the sub-chambers have a pressurized fluid admission valve connected to the outgoing fluid pumping line coming from hydraulic motor-pump mounted in the preceding chamber or, in the case of the first chamber, to the fluid line coming from the external pump, wherein each valve is actable to close at a predetermined fluid pressure which is incremental from the innermost sub-chamber to the outermost sub-chamber.
In another aspect, the wall of said at least one chamber composed of a set of sub-chambers is a multiple wall with space in-between the walls that define said sub-chambers.
Description of the drawings Figure 1 shows an example of embodiment of the present invention, of a multi-chamber pressure- increasing device, to produce ultra-high pressure within a predetermined volume in the innermost part of the device through an iterative process.
Figure 2 is a close-up of detail "A" of Figure 1 showing pressurized fluid admission valves for each space in between the multiwalls of the first chamber and for the motor part of the hydraulic motor-pump of the first chamber.
Detailed description of the invention The invention is an improvement to the system of the invention "Multichamber and Motor-pumps to generate ultra high pressure", in which, as already mentioned, there is one motor-pump for each chamber so that, as the chambers are concentric chambers, and from the outside towards the inside there is disposed a chamber then a motor-pump then another chamber with its corresponding motor-pump and this way arriving to the last chamber which is the most internal one and which supports the highest pressure. In this case the walls of every chamber are monolithic or do not have anything on the inside.
The pressure-increase mechanism of the subject-matter of the present invention is basically a modification to the "Multichamber and Motor-pumps To generate Ultra high Pressure", in that more efficiency is acquired with regards to size and operation, as it has several monolithic-walled chambers for every motor-pump that is installed, this applying mainly to those chambers which are located in the outer portion of the device.
Alternatively every chamber is designed with "multiple-walls" which allows, in the inner portions of its walls, to inject liquids at intermediate pressures between the pressure inside and the pressure outside of the "multiple-wall". Actually, the space in between the walls define sub-chambers within the chamber so in essence this multi-walled chambers variant is equivalent to the one with plural chambers for every motor-pump.
Figures 1 and 2 illustrate an example embodiment having three (3) sub-chambers in the first chamber, two (2) sub-chambers in the second, etc. The following describes a generic configuration of a multi-chamber pressure increasing device that includes m subchambers in the first chamber, k subchambers in the second subchamber, etc in accordance with an embodiment of the present invention. For the following description, the numerals are not reference numerals shown in the drawings, but rather numerals to aid in the description of the present invention.
Let's assume that the chambers can be built of "multiple" walls in the way described above, so we have that a first outer chamber which we shall name as chamber 1 is formed of several chambers or subchambers, for example chamber 1 is made up of subchambers 1,1;
1,2; ... 1,m. Likewise a second chamber which is disposed inside chamber 1 and which we shall name as chamber 2 is composed of subchambers 2,1; 2,2; ... 2,k; and a third chamber which is disposed inside chamber 1 and which we shall name as chamber 3 is composed of subchambers 3,1; 3,2; ... 3,j, and so on. The pressure-increasing process starts with an external pump having an outgoing pressurized liquid line that extends into the device up until chamber 1 and which can raise the pressure in subchamber 1,1 up to a predefined amount P1.
When the external pump begins to pump liquid at a lower pressure than P1, it will start to fill under pressure the whole system of subchambers, and when the pressure reaches P1,1 it is an indication that the outer subchamber 1,1 is full (see Note 1) and so a first pressurized liquid admission valve, which is disposed on the section of the outgoing pressurized liquid line which passes through subchamber 1,1 and we which shall name as valve 1,1 , then closes and the external pump continues transferring liquid to the other chambers, in particular to subchamber 1,2; and when the liquid inside subchamber 1,2 reaches a pressure equal to P1,2, higher than P1,1 but lower that Pl, a second pressurized liquid admission valve disposed on the section of the outgoing pressurized liquid line which passes through subchamber 1,2 and which we will name valve 1,2 is then closed and the pressure increasing process continues with subchamber 1,3 and in this way the process continues further until it reaches subchamber 1,m with a pressure P1 ,m = P 1 .
Then, to continue increasing the pressure within the more internal chambers, it is necessary to have a first hydraulic motor pump, i.e. a motor-pump 1, which is located within the subchamber 1,m and which starts to operate by filling the other more internal subchambers, in particular subchamber 2,1. As the first pumping of the motor-pump 1 is at a lower pressure than P2,k, equal to P2, which is another predefined pressure higher than P1, the pressure P1 at which chamber 1,m is declines a little because the motor part of motor-pump 1 discharges the liquid contained therein to the outside environment while the pump part of the motor-pump 1 ¨increases the pressure in the inner chambers.
Therefore it is necessary to wait for the external pump to recover pressure P1 in chamber 1,m in order to just then activate the motor-pump 1 again so that we may have a second pumping from the motor-pump 1 and, assuming that the pressure in chamber 2,k does not reach P2 yet, it will be necessary to wait again for the pressure P1 to recover within motor-pump 1 in order to activate again motor-pump 1 because the second pumping of motor pump 1 again lowers the pressure in which motor-pump 1 is submerged. The device continues to operate in this way until motor-pump manages to pump at a pressure P2,K equal to P2 inside chamber 2,k as well as the complete system of more internal subchambers.
Only then a second hydraulic motor pump, i.e. a motor pump 2, which is located within subchamber 2,k, starts to operate together with motor-pump 1 and the outer or external pump until chamber 3,j is filled with liquid at a pressure P3,j, which is a pressure equal to a predetermined value P3, and so on.
The gain in space and operational efficiency (utilization of one motor pump for several subchambers) decreases however towards the interior of the device so in a preferred embodiment of the invention the inner chambers do not have to be double-walled or triple-walled or more because as they are subject to higher pressure, hence their walls can be thinner in order to resist a pressure differential equal to Ph-Phl =P (Ph is the pressure on the inner side and Ph-1 is the pressure on the outer side).
Assuming the chambers are of cylindrical cross-section, when the thickness of the chamber is lower than a small percentage of the diameter (it can be any percentage from 5%
or 4% or 3% or any other small percentage) and resist a pressure difference which is the same or equal to P then it is not necessary to place several chambers, or a multiple-wall chamber, associated with each motor pump, because the reduction in overall size of the device and efficiency that may gained is no longer relevant.
The aforementioned pressure-increasing device according to the invention considered a generic configuration of multi-chamber pressure-increasing device according to the invention having m subchambers in the first chamber, k subchambers in the second chamber, j subchambers in the third chamber, etc. The accompanying Figures which will be described hereinafter illustrate a simple example embodiment of the invention having a first chamber composed of 3 sub-chambers, a second chamber composed of 2 sub-chamber and two more internal single-walled chambers.
The pressure-increase mechanism of the subject-matter of the present invention is basically a modification to the "Multichamber and Motor-pumps To generate Ultra high Pressure", in that more efficiency is acquired with regards to size and operation, as it has several monolithic-walled chambers for every motor-pump that is installed, this applying mainly to those chambers which are located in the outer portion of the device.
Alternatively every chamber is designed with "multiple-walls" which allows, in the inner portions of its walls, to inject liquids at intermediate pressures between the pressure inside and the pressure outside of the "multiple-wall". Actually, the space in between the walls define sub-chambers within the chamber so in essence this multi-walled chambers variant is equivalent to the one with plural chambers for every motor-pump.
Figures 1 and 2 illustrate an example embodiment having three (3) sub-chambers in the first chamber, two (2) sub-chambers in the second, etc. The following describes a generic configuration of a multi-chamber pressure increasing device that includes m subchambers in the first chamber, k subchambers in the second subchamber, etc in accordance with an embodiment of the present invention. For the following description, the numerals are not reference numerals shown in the drawings, but rather numerals to aid in the description of the present invention.
Let's assume that the chambers can be built of "multiple" walls in the way described above, so we have that a first outer chamber which we shall name as chamber 1 is formed of several chambers or subchambers, for example chamber 1 is made up of subchambers 1,1;
1,2; ... 1,m. Likewise a second chamber which is disposed inside chamber 1 and which we shall name as chamber 2 is composed of subchambers 2,1; 2,2; ... 2,k; and a third chamber which is disposed inside chamber 1 and which we shall name as chamber 3 is composed of subchambers 3,1; 3,2; ... 3,j, and so on. The pressure-increasing process starts with an external pump having an outgoing pressurized liquid line that extends into the device up until chamber 1 and which can raise the pressure in subchamber 1,1 up to a predefined amount P1.
When the external pump begins to pump liquid at a lower pressure than P1, it will start to fill under pressure the whole system of subchambers, and when the pressure reaches P1,1 it is an indication that the outer subchamber 1,1 is full (see Note 1) and so a first pressurized liquid admission valve, which is disposed on the section of the outgoing pressurized liquid line which passes through subchamber 1,1 and we which shall name as valve 1,1 , then closes and the external pump continues transferring liquid to the other chambers, in particular to subchamber 1,2; and when the liquid inside subchamber 1,2 reaches a pressure equal to P1,2, higher than P1,1 but lower that Pl, a second pressurized liquid admission valve disposed on the section of the outgoing pressurized liquid line which passes through subchamber 1,2 and which we will name valve 1,2 is then closed and the pressure increasing process continues with subchamber 1,3 and in this way the process continues further until it reaches subchamber 1,m with a pressure P1 ,m = P 1 .
Then, to continue increasing the pressure within the more internal chambers, it is necessary to have a first hydraulic motor pump, i.e. a motor-pump 1, which is located within the subchamber 1,m and which starts to operate by filling the other more internal subchambers, in particular subchamber 2,1. As the first pumping of the motor-pump 1 is at a lower pressure than P2,k, equal to P2, which is another predefined pressure higher than P1, the pressure P1 at which chamber 1,m is declines a little because the motor part of motor-pump 1 discharges the liquid contained therein to the outside environment while the pump part of the motor-pump 1 ¨increases the pressure in the inner chambers.
Therefore it is necessary to wait for the external pump to recover pressure P1 in chamber 1,m in order to just then activate the motor-pump 1 again so that we may have a second pumping from the motor-pump 1 and, assuming that the pressure in chamber 2,k does not reach P2 yet, it will be necessary to wait again for the pressure P1 to recover within motor-pump 1 in order to activate again motor-pump 1 because the second pumping of motor pump 1 again lowers the pressure in which motor-pump 1 is submerged. The device continues to operate in this way until motor-pump manages to pump at a pressure P2,K equal to P2 inside chamber 2,k as well as the complete system of more internal subchambers.
Only then a second hydraulic motor pump, i.e. a motor pump 2, which is located within subchamber 2,k, starts to operate together with motor-pump 1 and the outer or external pump until chamber 3,j is filled with liquid at a pressure P3,j, which is a pressure equal to a predetermined value P3, and so on.
The gain in space and operational efficiency (utilization of one motor pump for several subchambers) decreases however towards the interior of the device so in a preferred embodiment of the invention the inner chambers do not have to be double-walled or triple-walled or more because as they are subject to higher pressure, hence their walls can be thinner in order to resist a pressure differential equal to Ph-Phl =P (Ph is the pressure on the inner side and Ph-1 is the pressure on the outer side).
Assuming the chambers are of cylindrical cross-section, when the thickness of the chamber is lower than a small percentage of the diameter (it can be any percentage from 5%
or 4% or 3% or any other small percentage) and resist a pressure difference which is the same or equal to P then it is not necessary to place several chambers, or a multiple-wall chamber, associated with each motor pump, because the reduction in overall size of the device and efficiency that may gained is no longer relevant.
The aforementioned pressure-increasing device according to the invention considered a generic configuration of multi-chamber pressure-increasing device according to the invention having m subchambers in the first chamber, k subchambers in the second chamber, j subchambers in the third chamber, etc. The accompanying Figures which will be described hereinafter illustrate a simple example embodiment of the invention having a first chamber composed of 3 sub-chambers, a second chamber composed of 2 sub-chamber and two more internal single-walled chambers.
Referring again to Figure 1, the device illustrated is a simple example of one preferred embodiment of the invention, comprising an external pump and four concentric chambers in which the first chamber, or outermost chamber, has a multiple wall made up of three walls (10, 11, 12), the second chamber has a multiple wall of two walls (13, 14) and the following two inner chambers (15, 16) are single-walled chambers.
The external pump is connected to the first chamber or outermost chamber to fill, via a fluid pumping line, said first chamber with pressurized fluid. Further, the device comprises hydraulic motor-pumps in each chamber except for the last one, and comprises inlet valves to the "motor" part of each hydraulic motor pump. Furthermore, there are valves mounted within the pressurized fluid-injected space in between the walls of the multiple-walled chambers, as is shown in Detail A (see Figure 2) corresponding to the first chamber, each of which are activated at a certain predefined pressure so that they may be closed when the pressurized fluid injected into the space between walls reaches said predefined pressure.
Each hydraulic motor-pump consists of two cylinder-piston assemblies or two bellows that form the motor and pump parts of the hydraulic motor-pump, wherein the pump part and motor part of each hydraulic motor-pump are operably linked so that they operate simultaneously, either to be filled both at the same time with pressurized fluid or for discharging both at the same time pressurized fluid contained within the cylinders or bellows, the motor part driving the pump part in order for the latter to pump pressurized fluid from the same chamber in which it is mounted to a subsequent, more internal chamber through an outgoing fluid pumping line and at higher pressure than that of the chamber in which the hydraulic motor-pump is mounted. The motor part of each hydraulic motor-pump has a pressurized fluid discharge line towards the preceding chamber or, in the case of the first chamber, to the exterior environment where the external pump is located, thereby transferring the energy of the fluid from the motor part of the hydraulic motor-pump to the fluid within the pump part of the hydraulic motor-pump and thus producing fluid compression in the pump part and subsequent pumping of the same to the subsequent, more internal chamber within the device.
According to the preferred embodiment of the invention as shown in Figure 1, in any chamber the pressurized fluid pumped from the pump part of the hydraulic motor pump of the preceding chamber or, if it is the first chamber, from the external pump, flows into the chambers, filling the spaces inside the multi-wall if it has one, and it flows into the inlet valve of the hydraulic motor-pump of the chamber, wherein said inlet valve is initially open to the chamber and closed to the motor part of the hydraulic motor-pump until the moment when the pressure in the chamber reaches a determined value, which is when the fluid enters and fills the motor part. The innermost chamber of the device, where objects have to be subjected to ultra high pressure, lacks said inlet valve and the pressurized fluid simply flows straight into the chamber to fill it at high pressure.
The concept is a basic one, that is, that any chamber containing gas or liquid under pressure inside should have more resistance when the thickness of the walls is divided into a multiple-wall and the spaces let in between are submitted to intermediate pressures, as compared to when the chamber is made of a solid wall. So that when having two chambers, one with a solid wall and the other with a "multiple-wall" or a divided wall of the same dimensions and made of the same material, the chamber with a multiple-wall, which is the same as saying it is made up of various sub-chambers, resists more pressure that if it were a single chamber made of a thicker wall. The room used up by a multi-chamber device of this kind is reduced as is the number of motor pumps, in order to attain a pressure equal to Pn, than in the case where it has one motor pump per chamber.
It is comparable to a tube consisting of several concentric tubes or pipes as a pack, with intermediate pressures, so that it progresses from lower to higher pressure, the pressure increasing as it progresses from the outer tube to the inner tubes. It can resist more final pressure, which exceeds the tensile resistance of the material, than if a thicker walled tube is used made of the same material.
The multi-chamber pressure-increasing device must be equipped with safety valves and valves that allow the equipment to be taken apart, the same as in the one previously described invention of application 2331-2006. It should also carry all types of mechanisms that may allow to increase the temperature, to see through, etc.
Note 1: Any of the chambers is said to be full when the valve through which it is filled is closed by the pressure reached within the chamber. This is to say it is filled by liquid under pressure at a pressure which depends on the pressure said valve is set.
The external pump is connected to the first chamber or outermost chamber to fill, via a fluid pumping line, said first chamber with pressurized fluid. Further, the device comprises hydraulic motor-pumps in each chamber except for the last one, and comprises inlet valves to the "motor" part of each hydraulic motor pump. Furthermore, there are valves mounted within the pressurized fluid-injected space in between the walls of the multiple-walled chambers, as is shown in Detail A (see Figure 2) corresponding to the first chamber, each of which are activated at a certain predefined pressure so that they may be closed when the pressurized fluid injected into the space between walls reaches said predefined pressure.
Each hydraulic motor-pump consists of two cylinder-piston assemblies or two bellows that form the motor and pump parts of the hydraulic motor-pump, wherein the pump part and motor part of each hydraulic motor-pump are operably linked so that they operate simultaneously, either to be filled both at the same time with pressurized fluid or for discharging both at the same time pressurized fluid contained within the cylinders or bellows, the motor part driving the pump part in order for the latter to pump pressurized fluid from the same chamber in which it is mounted to a subsequent, more internal chamber through an outgoing fluid pumping line and at higher pressure than that of the chamber in which the hydraulic motor-pump is mounted. The motor part of each hydraulic motor-pump has a pressurized fluid discharge line towards the preceding chamber or, in the case of the first chamber, to the exterior environment where the external pump is located, thereby transferring the energy of the fluid from the motor part of the hydraulic motor-pump to the fluid within the pump part of the hydraulic motor-pump and thus producing fluid compression in the pump part and subsequent pumping of the same to the subsequent, more internal chamber within the device.
According to the preferred embodiment of the invention as shown in Figure 1, in any chamber the pressurized fluid pumped from the pump part of the hydraulic motor pump of the preceding chamber or, if it is the first chamber, from the external pump, flows into the chambers, filling the spaces inside the multi-wall if it has one, and it flows into the inlet valve of the hydraulic motor-pump of the chamber, wherein said inlet valve is initially open to the chamber and closed to the motor part of the hydraulic motor-pump until the moment when the pressure in the chamber reaches a determined value, which is when the fluid enters and fills the motor part. The innermost chamber of the device, where objects have to be subjected to ultra high pressure, lacks said inlet valve and the pressurized fluid simply flows straight into the chamber to fill it at high pressure.
The concept is a basic one, that is, that any chamber containing gas or liquid under pressure inside should have more resistance when the thickness of the walls is divided into a multiple-wall and the spaces let in between are submitted to intermediate pressures, as compared to when the chamber is made of a solid wall. So that when having two chambers, one with a solid wall and the other with a "multiple-wall" or a divided wall of the same dimensions and made of the same material, the chamber with a multiple-wall, which is the same as saying it is made up of various sub-chambers, resists more pressure that if it were a single chamber made of a thicker wall. The room used up by a multi-chamber device of this kind is reduced as is the number of motor pumps, in order to attain a pressure equal to Pn, than in the case where it has one motor pump per chamber.
It is comparable to a tube consisting of several concentric tubes or pipes as a pack, with intermediate pressures, so that it progresses from lower to higher pressure, the pressure increasing as it progresses from the outer tube to the inner tubes. It can resist more final pressure, which exceeds the tensile resistance of the material, than if a thicker walled tube is used made of the same material.
The multi-chamber pressure-increasing device must be equipped with safety valves and valves that allow the equipment to be taken apart, the same as in the one previously described invention of application 2331-2006. It should also carry all types of mechanisms that may allow to increase the temperature, to see through, etc.
Note 1: Any of the chambers is said to be full when the valve through which it is filled is closed by the pressure reached within the chamber. This is to say it is filled by liquid under pressure at a pressure which depends on the pressure said valve is set.
