Pressure operated windscreen wiper motor

The wiper motor has a reversing control valve and a double-action working cylinder in which two piston surfaces are connected by a toothed rod element to a toothed turning element. There are at least two control borings which can be passed over by the piston surfaces. One boring (2,2') of the c...

Beschreibung
Zusammenfassung:	The wiper motor has a reversing control valve and a double-action working cylinder in which two piston surfaces are connected by a toothed rod element to a toothed turning element. There are at least two control borings which can be passed over by the piston surfaces. One boring (2,2') of the control borings (1,1',2,2',3,3') of the operating device is at a set spacing from the end stop, and has a non-return valve (16) for unimpeded ventilation. The boring (3,3') close to the end stop comes out to a non-return valve (12) which locks in the ventilating direction and is fitted in parallel with an adjustable throttle (20).
