Claim:
1. A pilot valve or proportional valve, comprising: a valve drive and a valve body controlled by said valve drive; at least one valve seat that, together with said valve body delimits a flow cross section for a flow medium conducted through said pilot or proportional valve, said flow cross section being variable depending on a position of said valve body relative to said valve seat; said valve drive being a rotary drive having an actuator which is rotatable about a rotational axis and which is coupled with said valve body in such a manner that a position of said valve body relative to said valve seat changes depending on a rotary position of said actuator; an eccentric element mounted eccentrically on said rotational axis and rotationally related to said actuator; and a spring operated reset device engaged with said eccentric element, said spring operated reset device having a plunger that is pressed against said eccentric element by a spring, said spring operated reset device acting to rotate said eccentric element about said rotational axis into a single starting position substantially corresponding to an effective direction of said spring, wherein: said pilot or proportional valve further comprises a linear piston slide valve and said valve body being connected to said actuator through a connecting rod, said connecting rod being connected eccentrically to said actuator, relative to said rotational axis of said actuator.
