A solenoid valve, whose valve member is acted upon by a feed pressure in a closed setting by the feed pressure obtaining in an inlet duct. In order to render possible rapid switching operations a moving ancillary drive member is provided which is acted upon by a control pressure and which acts through an outlet duct in the opening direction, and hence against the feed pressure, on the valve member.

Solenoid valve with an ancillary drive member

The invention proposes a control device for multiway valves. It comprises two adjacently arranged solenoid means, which are respectively associated with a valve member to be driven. Each solenoid means comprises a coil. Outside the coils there is a yoke device for conduction of the magnetic fields, which are comprised in a yore part, which is associated with coils so that it may be pervaded by the magnetic fields of both coils. It is in this manner that an extremely compact design is rendered possible.

Control device for a multiway valve

A fluid power valve unit with at least one electromagnetic actuating block on a valve block which is adapted to be connected with a connection block having fluid power ducts therein. This connection block has means for connection with further connection blocks and contains electrical power and/or control conductors therein, and a plug connecting device connected with these conductors is respectively arranged on those sides of the connection block, which come into engagement with corresponding sides on connection with further connection blocks. Furthermore there are electrical connecting devices for the conductors in the connection block and connection of same with electrical terminals of the at least one actuating block. It is thus possible to dispense with wiring using separate wire elements on the valve unit even in the case of a number of such units being plugged together in rows, the electrical connections also being automatically produced on plugging together.
