Valve

摘要

A valve includes a spring with a spring force, an actuator with an actuator force which can act against the spring force, a pin which can be actuated by the actuator, a sealing element which can be coupled with the pin, and a seal seat such that the valve is closed when the sealing element rests against the seal seat. The pin can be moved in the direction of the sealing element by means of the actuator, and the pin can be moved in the direction away from the sealing element by means of the spring. The sealing element can be moved into an open position independently of the pin, wherein a fluid flow through the valve is released in the open position.

1. A valve, comprising:
a spring providing a spring force, an actuator providing an actuator force that acts counter to the spring force, a pin configured for actuation by the actuator, a sealing element and a sealing seat, wherein the valve is closed when the sealing element bears against the sealing seat, wherein the pin is moveable toward the sealing element by the actuator, and moveable away from the sealing element by the spring, wherein the sealing element is moveable independent from the pin into an open position in which a fluid flow through the valve is allowed, wherein the actuator comprises:
an electromagnet comprising a coil that surrounds a pole core, anda magnet armature moveable by the electromagnet, wherein the pin is coupled to the magnet armature and runs along a longitudinal axis of the electromagnet through the pole core wherein the magnet armature is arranged on a first side of the pole core and a separate stop element is arranged on an opposite second side of the pole core, the separate stop element configured to limit a movement of the pin toward the pole core, and wherein the stop element is formed from a harder material than the pole core.
