Title: Variable delivery volume vane pump
Inventor: DAIGO TOMIO
IPC: F04C2/344
Filed: 1982-09-30
Abstract: PURPOSE:To prevent generation of surging by a method wherein the excess pressure oil in the subpressure chamber of a sub piston, whose amount is corresponding to the delay of the response of a variable mechanism which generates a surge pressure, is escaped into a tank through a surge absorbing valve arranged in relation with the pump. CONSTITUTION:For instance, in case a cylinder is stopped suddenly at the end of the stroke thereof, the surge pressure is generated in the pump and the control pressure of the pressure chamber 23 of a main piston 4 shows a similar peak pressure. When the surge pressure of the control pressure has become larger than a set pressure for a spring 108, the poppet 107 of the surge absorbing valve A moves to the right as shown in the diagram and the control pressure of the sub pressure chamber 22 escapes to a tank port T. According to this operation, the surge pressure, exceeding a pump pressure corresponding to the set pressure, is removed. Accordingly, the best surge absorbing capacity may be maintained at all times in spite of the set pressure of the pump.
