Pressure fluid circuit

Abstract

Abstract PURPOSE: To enable to operate a plurality of sections in a pressure fluid circuit simultaneously independently of the level of load, by providing a pressure compensating valve on the outlet side of a pump, and communicating pilot chambers of respective sequence valves to each other via shuttle valves for selecting the highest fluid pressure. CONSTITUTION: The pressure compensating valve 5 is provided on the outlet side of a pump 3, and the sequence valves 29aW29c are provided respectively between the first partial circuits 15aW15c and second partial circuits 16aW16c. Pilot chambers 30aW30c of respective sequence valves 29aW29c are connected to each other via the shuttle valves 35, 36. With such an arrangement, the highest load pressure is exerted to pilot chambers 30aW30c of the respective sequence valves 29aW29c and pressures in the first partial circuits 15aW15c are rendered equal to each other. Therefore, a plurality of sections in a pressure fluid circuit can be operated simultaneously independently of the level of load. COPYRIGHT: (C)1981,JPO&Japio
