When the fluid of pump output enters c chambers and a chambers by (1) and (4) mouth of I groups (see Fig. 5)；It pushes and becomes energy piston 1 (39)
It moves upwards, then e chambers fluid is exported from (5) mouth.This process be pressurized/subtract one of stream mode：
1. the variation of input/output end pressure：By F1=P1A3And F2=P2A1, because becoming the active force phase at energy piston both ends
Deng i.e. F1=F2, ∴ P1A3=P2A1, enable∴P2=NP1, i.e. the pressure of output end is N times namely two of input terminal
The effective area ratio at end.
2. the variation of input/output terminal flow：Become energy piston I in Q1With V under effect1Speed moves upwards, i.e. V1=Q1/
A3, while V1=Q2/A1, ∴It enables∴Q2=Q1/ N, the i.e. flow of output end are 1/N times of input terminal,
Namely the inverse ratio of both ends effective area.
When the fluid of pump output enters c chambers by (1) mouth of I groups, push and become energy piston 1 and move upwards, then e chambers fluid from
(5) mouth exports, a chamber postal communication casees.This process is that supercharging/fuel tank subtracts the two of stream mode:
1. the variation of input/output end pressure：
By F '1=P1A2And F '2=P '2A1, because the active force for becoming energy piston both ends is equal, i.e. F '1=F '2, ∴ P1A2=
P’2A1, enable∴P’2=N ' P1。
2. the variation of input/output terminal flow：Similarly V '1=Q1/A2, while V '1=Q '2/A1, ∴It enables∴Q’2=Q1/N’。
When the fluid of pump output enters a chambers by (4) mouth of I groups, push and become energy piston I and move upwards, then e chambers fluid from
(5) mouth exports, c chamber copper fuel tanks.This process is to be pressurized/subtract the three of stream mode:
1. the variation of input/output end pressure：By F "1=P1A4And F "2=P "2A1, because becoming the effect at energy piston both ends
Power is equal, i.e. F "1=F "2, ∴ P1A4=P "2A1, enable∴P”2=N " P1。
2. the variation of input/output terminal flow：Similarly V "1=Q1/A4, while V "1=Q1/A4, ∴It enables∴Q”2=Q1/N”。
Two flow increasings/decompression
Using I group as research object, when the fluid of pump output enters e chambers by (5) mouth of I groups；Push become can piston I (39) to
Lower movement, then c chambers and a chambers fluid are exported from (1) mouth and (5).This process is one of flow increasing/pressure reducing mode:
1. the variation of input/output end pressure：If fluid acts on A1On active force be f1, act on A2On effect
Power is f2, by f1=P1A1And f2=P2A3, because the active force for becoming energy piston both ends is equal, i.e. f1=f2, ∴ P1A1=P2A3, enable∴P2=nP1, i.e. the pressure of output end is the effective area ratio at n times of input terminal namely both ends.
2. the variation of input/output terminal flow：Become energy piston I in q1With V under effect1Speed moves upwards, i.e. V1=q1/
A1, while V1=q2/A3, ∴It enables∴q2=q1/ n, the i.e. flow of output end are 1/n times of input terminal,
Namely the inverse ratio of both ends effective area.
When the fluid of pump output enters e chambers by I group (5) mouth；Push become can piston I move downward, then c chambers fluid from
(1) mouth exports, and a chambers lead to fuel tank.This process is the two of flow increasing/pressure reducing mode:
1. the variation of input/output end pressure：By f1=P1A1And f '2=P '2A2, because becoming the active force at energy piston both ends
It is equal, i.e. f1=f '2, ∴ P1A1=P '2A2, enable∴P’2=n ' P1, i.e. the pressure of output end is the n ' times of input terminal,
Namely the effective area ratio at both ends.
2. the variation of input/output terminal flow：Become energy piston I in q1With V under effect1Speed moves upwards, i.e. V1=q1/
A1, while V '1=q '2/A2, ∴It enables∴q’2=q1/ n ', the i.e. flow of output end are the 1/ of input terminal
The inverse ratio of n ' times namely both ends effective area.When the fluid of pump output enters e chambers by (5) mouth of I groups；Push become can piston I to
Lower movement, then a chambers fluid exported from (4) mouth, c chambers lead to fuel tank.This process is the three of flow increasing/pressure reducing mode:
1. the variation of input/output end pressure：By f "1=P1A1And f "2=P "2A4, because becoming the effect at energy piston both ends
Power is equal, i.e. f "1=f "2, ∴ P1A1=P "2A4, enable∴P”2=n " P1, i.e. the pressure of output end is input terminal
The effective area ratio at n " times namely both ends.
2. the variation of input/output terminal flow：Become energy piston I in q1With V under effect1Speed moves upwards, i.e. V1=q1/
A1, while V '1=q "2/A4, ∴It enables∴q”2=q1/ n ", the i.e. flow of output end are input terminal
The inverse ratio of 1/n " times namely both ends effective area.
In conclusion its input/output of both ends for becoming energy device is different by the difference of both ends active area.Its variable quantity
It is determined by both ends effective area ratio.The raising of its output pressure is synchronous with the reduction of output flow, that is, is pressed when exporting
Its output flow just reduces N times while power improves N times.Otherwise the increase of its output flow is the reduction with output pressure
Synchronous.It inputs constant with the gross energy of output.
To reduce overall structure size, it is limited to become the stroke of energy piston.So become to fill in and can be moved to the limit quickly
Position, output quantity stopped.Therefore two are needed to become energy device --- Ι and II：When become can piston I work will at the end of,
Become energy piston I I to have been started up；Become energy piston I immediately to start to reset.When become can piston I I work will at the end of, becoming can piston I
It has been started up.Two such becomes energy piston alternately, and continuous, unlimited output -- flow can be provided for hydraulic pressure executive item
With pressure.
