Abstract

Abstract Hydraulic fluid is fed through a storage charge valve and a change over valve to a hydro pneumatic storage tank. The charging valve has a third connection leading to working cylinders for a front loader. The latter can be used at any time providing that pressure is present in the storage tank. The change over valve has a regulator unit actuated by storage tank pressure, to enable all connections to the three point linkage, seat adjuster and differential cut out to be joined up. Should the pump pressure fall below a required value, the charging valve takes up a position to block off the front lifting circuit.
