ABSTRACT:
The output pressure of a piston pump is limited by opening of a pressure responsive limiting valve discharging pump fluid in jet form through an injector into the inflow stream in the suction intake conduit to the pump. The jet is discharged in a direction opposite to the inflow stream to reduce inflow pressure for pump pressure control purposes.
