2.2.5Integrated overflow valve with bleeder function

Task:

The task of the overflow valve is to protect the motor and gear unit against impermissible overpressure caused by the metering pump.

This function is produced by a spring-loaded ball.

A pressure relief mechanism for the bleeder function is provided.

Design and functional description (refer to Fig. No. 6 and 7)

Initially, the overflow valve illustrated under item 102 operates as a simple directly controlled safety valve. As soon as the pressure set with spring item 132 is exceeded, the effective pressure raises ball item 130. The liquid then flows off into the tank via hose connection item 128.
