Abstract
An apparatus for activation of a control valve is configurable as a slide, ball valve, rotary slide, poppet valve, or the like, and controls or regulates pressure-impacted media, for example, regulating the coolant volume stream of an internal combustion engine. A push piston linearly displaceable in a piston guide rigidly disposed on the flow housing, with an activation joint, is fastened onto the flow housing. A connecting rod is disposed in the activation joint. A push joint is disposed at the push piston end that lies opposite the activation joint, in which push joint the activation element of a control valve is displaceably and/or rotatably disposed. A reset spring is disposed adjacent to the push joint and acts on the push piston, in the direction of its longitudinal axis, so that the push piston always lies against the connecting rod without play, with the activation joint.
