Title: Hydraulic device of industrial vehicle
Inventor: HOSHINO NOBUAKI
IPC: B62D5/07
Filed: 1989-12-29
Abstract: PURPOSE:To perform capacity control of a pump with higher accuracy by leading the return pipeline of a relief valve disposed in a cargo bandling circuit, holding the pressure of the return pipeline by a pressure controlling valve, and opposing the holding pressure to the pressure of the cargo handling circuit to secondarily pilot-operate a flow rate changing valve. CONSTITUTION:In accordance with the operation load of a lift cylinder 3 (cargo handling actuator), for example, pressure of a cargo handling circuit 15 is raised, and by this pressure, a flow rate change valve 20 and a capacity control valve 30 are connectively pilot-operated. Even when a discharge oil quantity per rotation of a variable capacity type hydraulic pump 11 is enhanced to the maximum, an oil quantity passing a relief valve 5 is increased by the continuation of oil feed to the cylinder 3, for example, having reached an stroke end. When a holding pressure P4 of a return pipeline 51 independently lead from the valve 5 exceeds a determined value in accordance with this, the valve 20 is secondarily pilot-operated by the holding pressure opposed to the pressure of the circuit 15, and a variable capacity mechanism 40 is controlled through the connectively pilot-operated valve 30.
