Definitions
- the present invention relates to devices and methods for pulse ejection of medium.
- the aim of the present invention is to further develop the known solutions.
- One aspect of the invention relates to a device for pulse ejection of medium, with a media space for receiving medium, which is bounded by an ejection tube and a sleeve adjacent to the ejection tube to its ejection end sleeve, and a propellant space for receiving a propellant, the Media space in the region of the sleeve at least partially surrounds, wherein the sleeve is designed for movement between a printing position and an ejection position, wherein the sleeve seals the media space in the printing position at a conclusion relative to the propellant space and wherein in the ejection position, the sleeve Termination is spaced, so that a fluid connection for the passage of propellant from the propellant space in the media room exists.
- Another aspect of the invention relates to a method of pulse ejection of medium, comprising the steps of filling a media space of a pulse ejection device with medium, the media space being defined by an ejection tube and a sleeve adjacent the ejection tube opposite its ejection end , and filling a propellant space of the device with pressurized propellant, wherein the propellant space at least partially surrounds the media space in the region of the sleeve, wherein the sleeve is held after the filling steps in a printing position in which the sleeve closes the media space relative to the propellant space, the sleeve being released in a subsequent release step for movement from the pressure position to an ejection position where the sleeve is moved by the pressurized propellant, such that as a result of the movement the sleeve is spaced from the end and a e fluid communication is formed for the passage of propellant from the propellant space in the media space, wherein in a pulse step,
- the pressurized propellant itself can be used as a means for opening a "closure” which separates the propellant from the medium, such opening being not limited to the propellant and move the "shutter” in the same direction.
- the propellant drives the sleeve in the direction of the ejection end, so that the fluid connection is formed or released, the impulse ejection itself is caused by propellant that initially relaxes in the opposite direction.
- the device according to the invention makes it possible to provide the propellant space around the media space, so that a more compact design is possible in comparison with a known device for impulse ejection, which the media space and propellant space are arranged one behind the other.
- the invention has less recoil at the same pulse power compared to known pulse ejection devices, which is of particular interest in a hand-held device. Taking the further same recoil into account, a larger amount of medium can be pulse-ejected with the device according to the invention and the method according to the invention.
- the sleeve has a collar portion which encloses the ejection tube in an area. With the overlap of sleeve and ejection tube in the collar region, a coupling and a connection between the sleeve and the ejection tube, which can be sealed, for example by a sliding seal or the like, results in a movable manner.
- the collar region is arranged between the propellant space and a pressure chamber, wherein the pressure chamber is designed to receive a pressurized fluid, so that the sleeve is pressed onto the closure by a pressure in the pressure chamber.
- the pressurized fluid gas and / or liquid
- the pressure of the fluid thus ensures the sealing effect of sleeve and termination.
- the collar region has a first end face opposite the pressure chamber and a second end face opposite the propellant space, which is smaller than the first end face.
- the desired resultant force (which presses the sleeve towards the end) can be achieved when the fluid in the pressure chamber has a pressure sufficiently high than the propellant in the propellant space.
- the collar region is provided with at least one non-return valve, which is designed for a passage of propellant from the pressure chamber to the propellant space.
- the check valve allows blowing agent is first introduced into the pressure chamber and from there into the propellant space, without the propellant space would immediately suffer a corresponding pressure drop at a pressure release in the pressure chamber.
- the sleeve has on its inner side in the region of the collar region a shoulder, where an inner cross section of the sleeve substantially corresponds to an inner cross section of the ejection tube. It has been found that the inner cross-sections corresponding to one another (ie inner walls that are in alignment with one another) are advantageous for pulse ejection, which could possibly be based on the avoidance of turbulence.
- the shoulder is formed by a projection and widens the inner cross section of the sleeve at least in a part of the sleeve towards the conclusion.
- a vorzugierir continuous transition to another inner cross-section has been shown as not adversely affecting the pulse output, with the larger inner cross-section, a larger volume of the media space can be achieved without having to make the device itself longer.
- the sleeve can be understood with guide elements, so that, for example, a relative rotation of the sleeve within the jacket tube or relative to the ejection tube can be prevented.
- the differential pressure force is used to push the sleeve to the conclusion.
- another force or bias can be provided, for example by a corresponding spring (preferably in the pressure chamber) or by magnets, either attractive (eg in sleeve and Termination) or repellent (eg in the pressure chamber, media room or jacket tube on the one hand and in or on the sleeve on the other hand) are arranged.
- the release takes place by a rapid pressure drop in the pressure chamber, so that the pressure in the propellant space removes the sleeve from the conclusion.
- the invention is not limited to this and other types of release may be used, including a mechanical lock which is released for release.
- the gap between the sleeve and the jacket tube is (completely) sealed as long as passage of propellant is limited or impeded to such an extent that no significant amount of propellant "leaks" through this gap during pulse ejection
- the pressure chamber is provided with a drain, which is not necessarily also for the supply of propellant or other fluid must be designed.
- One way to further develop the seal between the sleeve and the jacket tube, if provided, is to form the seal with a recoil valve function so that propellant supplied to the pressure chamber will pass through or past the seal Propellant can reach space to build pressure there, but can not penetrate in the opposite direction from the propellant space in the (pressure unpressurized) pressure chamber.
- a seal provided between the sleeve and the ejection tube is not limited to abutting the outer surface of the ejection tube and the inner surface of the sleeve, such as an O-ring. Another possibility is, for example, to provide a bellows or the like between the sleeve and the ejection tube to the connection.
- this pressure relief can be designed so that the pressure chamber is not completely depressurized (such as by maintaining an opening to the environment), but that a defined amount of fluid remains in the pressure chamber, the - Especially when the fluid is a gas - as a buffer braking effect on the sleeve exerts to prevent or at least mitigate a hitting or striking the sleeve at about the ejection tube.
- the device according to the invention is designed for hand-held use (preferably fully mobile), although the invention may be practiced in a vehicle-mounted or fixed-mounted device.
- the ejection tube, the sleeve and the jacket tube are formed in (circular) circular shape in cross-section, although other shapes are also possible, including asymmetric shapes.
- a device for pulse ejection of medium comprising a device body having a media space for receiving medium, which is at least partially bounded by an ejection tube, and a propellant space for receiving a propellant for impulsively expelling the medium by a medium Ejection end of the ejection tube, a trigger handle attached to the device body for holding the device with a first hand of a user and for triggering the pulse ejection and a handle attached to the device body for holding the device with a second hand of the user, wherein the handle and / or or the release handle are configured for pivoting about an axis parallel to an ejection direction of the pulse ejection.
- a hand-held pulse ejection device due to the recoil occurring at the pulse ejection, beyond a certain size of the device, there is a general need to hold the device securely with two hands. It has been found that regardless of the question of whether the user is right-handed or left-handed, different users already have different preferences as to how the trigger handle and grab handle are aligned relative to one another. With an appropriate adjustment for this orientation, it was found that the attitude and handling of the device could be improved. In general, the pulse ejection device is held in the hip so that the handling is not comparable to that of a rifle usually placed in the shoulder for aiming.
- the device comprises a medium feed to the media space obturator, the handle being configured for displacement along the ejection tube between a forward position and a closed position, the handle being coupled to the obturator such that a displacement of the handle in the passage position, the obturator for a passage of medium open and by a displacement of the handle in the closed position the obturator can be closed.
- the medium can be supplied to the media room without the hands having to be taken from the grab handle and the trigger handle. If the user needs to take one of the hands off a handle (such as the grab handle) to control the obturator, the user may forget to hold the grab handle again and already trigger the impulse ejection. Due to the recoil, this can lead to an uncontrolled reaction ("bucking") of the device, which is associated in particular with a risk of injury to the user.
- bucking uncontrolled reaction
- the pivoting handle is equipped with a fixing device that allows either a fixation or a release for pivoting. With the fixation, the user can set a once set as desired pivot position on further.
- the pivoting handle may be provided with a guide that limits the pivoting to certain areas.
- a guide that limits the pivoting to certain areas.
- the device according to the invention has one or more stops for the pivotable handle, which limit the pivoting, although a completely free pivoting is not excluded at least for the handle.

- Fig. 6 is a schematic flow diagram of a method according to the invention for pulse ejection of medium.
- Fig. 1 shows a schematic illustration of a first embodiment of the device 10 according to the invention for the pulse ejection of medium in a state before ejection.
- the device 10 for pulse ejection has a media space 1, which serves to receive medium.
- the medium can be, for example, a liquid (for example water, optionally mixed with additives or the like). Another possibility is to provide suitable medium as a medium with sufficiently small particle size. Since the invention does not necessarily differ from known solutions for pulse ejection in terms of the medium itself, can be dispensed with a further discussion of the medium here, since the skilled person is sufficiently familiar with the properties and requirements by means of pulse ejected media.
- the media space 1 is delimited by an ejection tube 2, wherein the ejection tube 2 in the ejection direction (in the illustration of Fig. 1 to the left) even at its ejection end (not shown in Fig. 1, see Fig. 5) open or by a known membrane or the like may be closed against accidental leakage of medium.
- a sleeve 13 which also surrounds the media space 1.
- Media space 1 and sleeve 3 extend to a conclusion 6, to which the sleeve 3 sealingly in the state of Fig. 1.
- the media space thus extends from the end 6 through the sleeve 3 and the ejection tube 2 through to the ejection end of the ejection tube 2 or to another closure region of the ejection tube 2 (not shown in Fig. 1). It should be noted that the media space 1 does not necessarily have to be completely filled with medium before ejection. The ejection of the medium is possible as long as medium is present in an amount and distribution which is a "fuming" of the propellant (see below) prevented. However, this also applies to conventional devices for pulse ejection of medium.
- the sleeve 13 encloses together with a sleeve 13 receiving the jacket tube 14 and the end 6 a propellant space 5.
- a propellant space 5 In the state shown in Fig. 1, there is no fluid connection between the propellant space 5 and the media space 1, since the sleeve 13 sealingly Termination 6 is present.
- the sleeve 13 expands so that it substantially fills the region between an outer surface of the ejection tube 2 and an inner surface of the jacket tube 14 in one section , With this expansion, the sleeve has an end face 42 opposite to the propellant space 5, which corresponds to the cross section of the propellant space 5.
- the sleeve 13 is provided in this area for additional sealing against the passage of propellant with a seal 17 between the sleeve 13 and jacket tube 14.
- a seal 17 between the sleeve 13 and jacket tube 14 On the side facing away from the propellant space 5 side of the sleeve (in the direction of the discharge end) enclose the ejection tube 2, the casing tube 14 and the sleeve 13 a pressure chamber 9.
- the sleeve 13 has opposite the pressure chamber 9 an end face 41, which corresponds to the cross section of the pressure chamber 9 , A seal 19 between the sleeve 13 and the ejection tube 2 seals against an escape of propellant (see below) from the pressure chamber 9 into the media space 1.
- the sleeve 13 is arranged to be movable relative to the ejection tube 2 along a central or longitudinal axis of the ejection tube 2, so that the size of the pressure chamber 9 is variable.
- the movement of the sleeve 13 relative to the ejection tube 2 is limited by the conclusion 6 on the one hand and the ejection tube 2 itself on the other.
- the sleeve 13 has at a distance from the end of the ejection tube 2 an inner circumferential shoulder 47, which is designed so that the clear cross section (or inner cross section) of the shoulder 47 corresponds to the clear cross section of the ejection tube 2. It is not necessary here that during a movement of the sleeve 13 (see FIG.
- the shoulder 47 abuts or strikes the end of the ejection tube 2, although this is not excluded.
- the inner wall of the sleeve 13 and the inner wall of the ejection tube 2 would be at a such attack in flight.
- the shoulder 47 is hereby designed as a projection, so that the clear cross-section of the sleeve widens away in the direction away from the discharge end. In the present embodiment, this expansion takes place such that the inner cross section in front of and behind the projection is identical, even if this is not necessary.
- the jacket tube 14 has in the region of the pressure chamber 9 a supply line 3 to the pressure chamber 9, through which the pressure chamber 9 can be provided with pressurized propellant 9.
- the sleeve 13 has a passage 8 through the collar portion 18.
- the passage 8 connects the pressure chamber 9 fluidly with the propellant space 5 and has a check valve 45, which allows only one passage from the pressure chamber 9 to the propellant space 5 and blocks in the opposite direction.
- Fig. 1 only one such passage 8 is shown, wherein the device according to the invention but quite a plurality of such passages 8 with check valves 45 may be distributed to the circumference of the sleeve 13.
- the media space 1 is filled with medium and a desired pressure of the propellant (fluid, preferably gas, for example air) in pressure chamber 9 and propellant space 5 constructed.
- the propellant fluid, preferably gas, for example air
- the pressure of the propellant in the pressure chamber 9 is reduced (preferably abruptly), then the pressure of the propellant still present in the propellant space 5 drives the sleeve 13 in the direction of the ejection tube 2 (in FIG. 1 to the left), so that the sleeve 13 is removed from the end 6 and thus a fluid connection (see Fig. 2) between the propellant space 5 and the media space 1 is formed.
- Fig. 2 shows a schematic illustration of a first embodiment of the device 10 according to the invention for pulse ejection of medium in a state of ejection.
- the pressurized propellant flows, as indicated by the arrows 15.
- the relaxing propellant expels the present in the media room 1 medium, so that it comes to the pulse ejection of the medium from the media space 1 out through the sleeve 13 and the ejection tube 2, as indicated by the arrow 16.
- FIG. 3 shows a schematic illustration of a second embodiment of the device 20 according to the invention for pulse ejection of medium in a state before ejection comparable to the illustration of FIG. 1.
- the basic structure of the device 20 shown in Fig. 3 corresponds to that of the device 10 shown in Figs. 1 and 2.
- Corresponding elements are insofar provided with identical reference numerals. Unless otherwise explained below, the above applies to Fig. 1 and 2 executed accordingly also for the second embodiment.
- the second embodiment differs from the first embodiment of the device according to the invention initially in the deviating embodiment of the sleeve 23.
- the sleeve 23 has in its collar portion 28, which connects to the region between the ejection tube 2 and a jacket tube 24, a shoulder 48 in which the internal cross-section of the sleeve 23 from a region which surrounds the ejection tube 2 and substantially abuts the outside of the ejection tube 2, reduced in one step to an internal cross-section which corresponds to that of the ejection tube 2.
- the inner cross section of the sleeve 23 does not expand toward the end 6 but remains constant.
- the sleeve 23 has an end face 43 opposite the pressure chamber 9 and a further end face 44 opposite to the propellant space 5.
- the end face 44 is larger than the end face 43.
- the jacket tube 24 has a feed line 3 to the pressure chamber 9, through which the interior of the pressure chamber 9 can be pressurized.
- the jacket tube 24 (unlike the above jacket tube 14) comprises a further supply line 11 to the propellant space 5, through which the propellant space 5 can be supplied independently of the pressure chamber with pressurized propellant.
- the sleeve 23 has no passage for a fluidic connection of pressure chamber 9 and propellant space 5.
- this resultant force is reversed in view of the pressure remaining in the propellant space 5 due to a pressure drop in the pressure chamber 5, so that the sleeve 23 is moved in the direction of the ejection end and thus allows the fluid connection between the propellant space 5 and the media space 1.
- FIG. 4 shows a schematic illustration of a third embodiment of the device according to the invention for pulse ejection of medium in a state before ejection comparable to the illustration of FIG. 1 or FIG. 3.
- the basic structure of the device 30 shown in Fig. 4 corresponds to that of the device 10 shown in Figs. 1 and 2.
- Corresponding elements are insofar provided with identical reference numerals. Unless otherwise explained below, the above applies to Fig. 1 and 2 executed accordingly also for the third embodiment.
- the sleeve 33 of the third embodiment largely corresponds in its basic form of the sleeve 13 of the first embodiment. Unlike this, the Sleeve 33 only on its inside a seal 19 for sealing between the sleeve 33 and the ejection tube 2, but not on the outside, which is directed to a jacket tube 34. Only by the concerns of the sleeve 33 on the inner wall of the jacket tube 34 results in a certain fluid resistance to passage of propellant between the pressure chamber 9 and propellant space 5. Similar to the second embodiment, the sleeve 33 itself has no passage from the pressure chamber 9 to the propellant space fifth on.
- the jacket tube 34 has, like the jacket tubes 14 and 24 of the first and second embodiments, a supply line 3 to the pressure chamber 9. Unlike the jacket tubes 14 and 24 of the other embodiments, the jacket tube 34 itself comprises two passages 12 which - each provided with a check valve 46 - allow passage of pressurized propellant from the pressure chamber 9 to the propellant space 5 and lock in the opposite direction.
- Fig. 4 two passages 12 are shown with respective check valve 46, which by design, a passage 12 or more passages 12 can be provided. If necessary, one or more passages through the sleeve can be additionally provided, as described above with reference to the first embodiment.
- the collar portion 38 of the sleeve 33 allows due to the absence of an actual seal between the sleeve 33 and jacket tube 34 in addition to the passages 12 a passage of propellant. It is also possible to modify the present third embodiment by providing a seal between the sleeve and the casing tube as in the first and second embodiments.
- the third exemplary embodiment has one or more springs 49 which, even without the pressure of the propellant abutting, bias the sleeve 33 towards the end 6.
- the device according to the invention can provide an automatic closure of this shut-off element, as far as a shut-off device, for example a valve or the like, is provided for filling the media space with medium, for instance a desired degree of filling independent of not to exceed an operation by the user and / or to prevent unwanted filling of the media room in terms of a safety aspect. It is possible in this case to couple a triggering of the pulse output to the previous closure or in turn to couple the closure in turn to the triggering (eg in the sense that a supply of medium to a release by the operator is prevented after a pulse discharge ).
- Fig. 5 shows a schematic perspective view of an embodiment of the inventive device 50 for pulse ejection of medium.
- the pulse ejection device 50 comprises a device body 51.
- This device body 51 has a media space (not shown, for example, see Figs. 1 to 4) for receiving media. Similar to the embodiments discussed above, the media space is limited at least in part by an ejection tube (not shown, see for example Figures 1 to 4).
- the device body also has a propellant space (not shown, see, for example, Fig. 1 to 4), in which propellant for the pulse-like expulsion of the medium can be kept.
- the device 50 includes a trigger handle 52 attached to the device body 51 that is comparable to conventional hand held pulse ejection devices for holding the device 50 with a first hand of the user and for triggering the pulse ejection. As is also known from conventional hand-held devices, the device 50 includes a handle 53 for holding the device 50 with a second hand of the user.
- the device 50 of this embodiment is characterized in that the handle 53 is designed for pivoting about a longitudinal axis of the device 50 (or of the ejection tube), as indicated by the double arrow 58.
- This pivoting allows the handle 53 to be pivoted respectively by, for example, 90 ° from a plane defined by the trigger handle and the longitudinal axis of the device (ie about the plane of the drawing of FIG. 5) to adjust the device 50 to the wishes of the particular user Can be left or right handed.
- the release handle 52 can be designed for pivoting.
- the handle 53 in this embodiment has an over-holding function for operating a shut-off device 54 of the device 50.
- the obturator opens or closes a supply line 55 for medium to the media room 1 of the device.
- the handle 53 is configured for displacement along the ejection tube (between the ejection end 4 and the trigger handle 52) between a passage position and a closing position and is coupled to the obturator 54 such that by a displacement of the handle 53 into the passage position the obturator 54 for a passage of medium open and by a displacement of the handle 53 in the closed position the obturator 54 can be closed. This shift is indicated by the double arrows 59.
- the device 50 has a sheath 56 which is movably mounted on the device body 51.
- This sheath 56 has a groove 57 into which engages a coupled to the obturator 54 transmission mechanism, so that the transmission of the longitudinal displacement is independent of the pivot state of the handle 53.
- the obturator 54 when operating the obturator 54 by the handle 53 as described above, the obturator 54 may also be configured (not shown here) that a further passage of medium is prevented, such as when, for example, a predefined degree of filling is reached.
- the operation by the handle 53 temporarily overriding blocking can also in connection with a Triggering the pulse output to be connected, wherein - for example, until a further back and forth movement of the holder handle 53 - a media passage is suppressed to a mglw. to prevent unwanted immediate filling with medium.
- An alternative to this may be to provide a backup insofar as that triggering the pulse output only in the case of a corresponding (closing the obturator) position of the holder handle 53 is possible.
- Fig. 6 shows a schematic flow diagram of a method according to the invention for pulse ejection of medium.
- a media space of a pulse ejection device is filled with medium.
- a media space of a pulse ejection device is filled with medium.
- a propellant space of the device is filled with pressurized propellant.
- a sleeve of the device which partially encloses the media space is held in a print position after the steps of filling 101, 102 in which the sleeve seals the media space from the propellant space.
- the propellant space or, at first, the media space can be filled first, followed by further fillings in each case. It is also possible that the steps 101 and 102 are performed at least partially in parallel and simultaneously with each other.
- a subsequent release step 103 the sleeve is released for movement from the print position to an ejection position.
- the sleeve is moved by the pressurized propellant, so that due to the movement of the sleeve from a conclusion, where it was designed to seal between the media space and propellant space, is spaced, so that a fluid connection for the passage of propellant from the Forms propellant space in the media room.
- the pressurized propellant passes through a pulse step 104 and drives the medium in front of it, so that the medium is ejected in a pulsed manner from an ejection end of the device.
