ELECTROMAGNETICALLY OPERABLE VALVE GEAR

PURPOSE: To realize precise pressure adjustment at any ratio of a load pressure to an inlet pressure by setting a throttle passageway for connecting a pilot control chamber and an inlet chamber to a specified dimension. CONSTITUTION: When an actuation electromagnet 3 is excited, an armature 2 is dra...

Zusammenfassung:	PURPOSE: To realize precise pressure adjustment at any ratio of a load pressure to an inlet pressure by setting a throttle passageway for connecting a pilot control chamber and an inlet chamber to a specified dimension. CONSTITUTION: When an actuation electromagnet 3 is excited, an armature 2 is drawn in, and pilot valves 4, 5 are opened, thus a pressure medium flows into an actuation chamber 32. When an exciting current and the opening cross section are small, the amount of the pressure medium just the same as that flowing to the load facility through the pilot valves 4, 5 can flows into a pilot control chamber 40 through a throttle valve 34. If the exciting current is higher, a larger amount of the pressure medium flows out from the pilot control chamber 40 through the pilot valves 4, 5, whereby the pressure in the pilot control chamber 40 decreases, thus main valves 45, 46 are opened.
