Bosch Rexroth Radial Piston Pumps

Bosch Rexroth Radial Piston Pumps are characterised by very high operating pressures of up to 700 bar. The volume flows of the individual pistons can be used for various tasks.

Bosch Rexroth PR4-1X Product Description

 Assembly

The pumps are valve-controlled, self-priming radial piston pumps with fixed displacement.

They consist essentially of the housing (1), eccentric shaft (2) and pump elements (3), with suction valve (4), pressure valve (5) and piston (6).

 

Suction and displacement process

Pistons (6) are arranged radially to the eccentric shaft (2). The piston (6) is guided in cylinder (7) and pressed against the eccentric (2) by the spring (8). During the downward movement of piston (6), the working chamber (9) in the cylinder (7) increases in size. The resulting negative pressure lifts the suction valve plate (4.1) from the sealing edge. This opens the connection from the suction chamber (10) to the working chamber (9). The working chamber fills with fluid. During the upward movement of piston (6), the suction valve closes and the pressure valve (5) opens. Fluid can now flow to the system via pressure port (P).

Bosch Rexroth PR4-3X Product Description

Assembly

The pumps are valve-controlled, self-priming radial piston pumps with fixed displacement.

They consist essentially of the housing (1), eccentric shaft (2) and 3, 5 or 10 pump elements (3), with suction valve (4), pressure valve (5) and piston (6).

 

Suction and displacement procedure

The pistons (6) are arranged radially to the eccentric shaft (2). The hollow piston (6) with the suction valve (4) is guided in a cylinder (7) and pressed onto the eccentric (2) by the spring (8). The radius of the piston running surface corresponds to the eccentric radius. The cylinder (7) provides sealing against a hemispherical element (9).

In downward movements of the piston (6), the working space (10) in the cylinder (7) is enlarged. Due to the resulting negative overpressure, the suction valve plate is raised from the sealing lip. Simultaneously, the connection from the suction chamber (12) to the working chamber (10) is realized by means of a radial groove (11) in the eccentric (2).

The working chamber is filled with fluid. In upward movements of the piston (6), the suction valve (4) is closed and the pressure valve (5) is opened. The fluid now flows to the system via the pressure port (P).
