Abstract
An electromagnet directional valve assembly including a common base element with valve seats between fluid connections in sockets, valves each including a valve body and magnetic tube of valve actuator fluidically sealed to the sockets, a plurality of magnetic jackets separate from the valve actuator and joined in groups, and a cover plate joined to the base element for clamping the valves and jackets therebetween.
Claims23
An electromagnetic directional control valve assembly comprising:
- a common base element having fluidic pressure connection paths, a plurality of sockets, a valve sealing seat in each of said sockets fluidically between one pressure connection path and at least one load connection path;
- a common cover plate;
- a plurality of electromagnetic directional control valves between said common base element and said common cover plate, each including a valve body, valve actuator, said valve actuator including an armature and magnetic tube surrounding said armature and forming a fluid tight contact with said sockets;
- a plurality of magnetic jackets between said common base element and said common cover plate, separate from and for each valve actuator, said magnetic jackets joined to form a coherent magnetic jacket component common to several actuators, the distances between the individual magnet jackets corresponding to distance between said sockets;
- and
- clamping means for clamping said valve actuators and said magnetic jacket components between said common base element and cover plate.
