Abstract

1389527 Valves ROBERT BOSCH GmbH 29 Jan 1973 [9 Feb 1972] 4482/73 Heading F2V Fluid from a pump (not shown) is supplied through a bore 12 and a non-return valve 25 to an accumulator 21 until the pressure in a passage 22 is sufficient to displace a valve 6 to the right against a spring load and connect the pump to a return line 9 until the pressure in the accumulator falls to a lower value, the spring load being produced by the combination of a diaphragm spring 32 and a helical spring 36 to provide a snap-action. The springs are prestressed in the limiting position in which the pump supplies the accumulator. In a second embodiment, the valve is mounted in the same casing as a radial piston pump.
