Compressed air maintenance unit, and consumer control device equipped with the same

摘要

The compressed air-maintenance device (2) has an electrically actuatable switching valve (14) which has a power supply unit (16) and a work output (17), where the power supply unit is connected with a compressed air source (P). A housing outlet (7) is connected with an external consumer device (A). The switching valve is formed as two by two-way valve of normally open type and is biased by a spring unit (19) in the open position, so that it always takes up the open position in the absence of the electrical switching signal.
