Pump discharge lines 29 and 30 are connected to check valves 31 and 32, respectively. are connected to each other. This device increases the discharge volume of the pump fluid. Pressure fluctuations can be reduced.

In the embodiment of the apparatus shown in FIG. 8 having four pumps according to the invention, In the pump, a drum 34 is arranged and a sealed end of the flexible hose 2 is fixed. It has a common chamber 33 in which it is located. The vertical axis of flexible hose 2 is aligned with the axis of drum 3. They are evenly distributed around the area. The chamber 33 communicates with a working fluid supply fi35 and They communicate with the surroundings via valves 36 and 37, respectively. Each pump has a pump fluid in communication with the supply sources 39.40, 41, 42 and the discharge lines 43.44.45.4. 6, each having a chamber 38 communicating with the chamber 6.

The pump operates as follows.

The working fluid enters the chamber 6 from the supply R10 via the intervalve 8. Hose 2 It is fed out from the drum 3 which rotates freely on the shaft 3 and reaches the end wall surface 14. . The pump is now ready for operation. A valve 9 that communicates the chamber 6 with the surroundings and A valve 11 is opened which communicates the chamber 7 with the pump fluid supply mfi 12. hose 20 The sealed end is wrapped around the drum when the drum is rotated by the driving means. and the hose 2 displaces the working fluid from the chamber 6. Pressure drop occurs in chamber 7 However, pump fluid is drawn into the chamber from source 12. Hose 2 is on the opposite side, end 5 When the chamber 7 reaches its end position near the point where it is fixed, the chamber 7 is filled with pump fluid. Therefore, it is satisfied. Valves 9 and 11 are closed and valves 8 and 13 are opened. Ru. Due to the pressure, the working fluid flows from the supply R1O into the chamber 6 and the hose 2 is forced into the wall at the end. Move it to 14. Hose 2 is unwound from a freely rotating drum and pumped The pump fluid is moved from chamber 7 via valve 13 to the discharge line. Continuing above The cycle is repeated.

The valve 21 of the pump fluid supply m[22 is opened and discharged. The output line valve 23 is closed. Pump fluid enters chamber 20 under gravity. Once that is filled, the pump is ready for operation. Valve 21 is closed and valve 2 3 can be opened. When the hose 2 is wrapped around the drum 3, the pump fluid flows through the valve 2 3 and into the discharge line.

At the same time, a pressure drop occurs within chamber 19. Then the valve 23 is closed and the valve 23 is closed. 21 can be opened. The pressure in chamber 20 will be greater than the pressure in chamber 19. drum 3 is released from the drive means. Due to the pressure difference between the two chambers, the hose 2 is removed from the drum 3. It begins to unwind freely in the direction of the wall surface 14 at the end.

The volume of chamber 20 increases and pump fluid is drawn into it.

This cycle is then repeated.

The apparatus shown in FIG. 7 has drums 3 each mounted on a coaxial shaft 4. It consists of two pumps. The operation of each pump is based on the operation of the pump described above. It is similar to the work. While one pump suctions the cylinder, the other pump A valve 28 connects the working fluid source 27 and each of the pumps to each other. It communicates with the rooms alternately. Clutch members 25 and 26 of drum 3 are alternately engaged with a clutch member 24 connected to the drive means.
