Classification and function of Rexroth pressure control valves
1. Rexroth relief valve
Overflow, pressure stabilizer, which is used to regulate and maintain the oil supply pressure of the pump while overflowing the excess oil in the system. When the regulated pressure is reached, the hydraulic system is controlled to keep it in a constant state. Relief valves for overload protection are called safety valves. ...

Rexroth hydraulic pump - gear pump common problems and solutions
1. Trapped oil
(1) Causes
The trapped oil of the gear pump is caused by the overlap coefficient of the gear design, as shown in the figure below, assuming that the length of the meshing line of the gear in the actual meshing is l and the tooth pitch is t0, then the overlap coefficient of the gear meshing is ε=l/t0. This overlap coefficient has such a ...
