Abstract

1427466 Valves ROBERT BOSCH GmbH 23 Jan 1974 03076/74 Heading F2V Fluid in a supply line 15 is allowed to pass directly to a return line 16 by a valve 14 which is displaced against a spring 19 by the pressure drop across throttles 25, 23 when a valve 45 is in the neutral position shown, When the valve 45 is displaced to either side of the neutral position to connect load ports 32, 33 to the supply and return lines, a passage between control chambers 36, 37 is partly closed and the flow through the throttle 23 is reduced so that the valve 14 is displaced by its spring to increase the pressure in the line 15. The flow to the load increases the pressure drop across the throttle 25 and reduces the flow through the throttle 23 to prevent pressure peaks in the line 15.
