An electric switching valve for controlling a pneumatic actuator element includes a housing with a ventilation connection channel, a vacuum connection channel and a consumer connection channel. The vacuum connection channel comprises a first valve seat and the ventilation connection channel comprises a second valve seat. An electromagnetic drive is arranged in the housing. The electromagnetic drive is configured so that a magnetic armature is translationally movable in a passage channel to form a valve closure body for each of the vacuum connection channel and the ventilation connection channel. A cross-sectional constriction device is disposed in the ventilation connection channel.

Electrical switching valve

A holder for electro-pneumatic components for vehicles provides for a base plate with fastening elements for fastening the holder in the vehicle. Holding elements for releasable holding the electro-pneumatic components are connected to the base plate. The fixing elements each have two holding arms designed as click-in elements. Further, a fixing element in the form of a small elastic plate, such as a rubber disc, is provided. The fixing element presses the electro-pneumatic component against an abutment for a vibration-resistant fixation.

Holder for electro-pneumatic components

Valve arrangement for pressure regulation of fuel introduction in an internal combustion engine having a pressure regulation and a shutoff function that can be actuated by an electromagnetic drive. A housing is provided with at least one inlet connection and at least one outlet connection, which are connected to one another by a connection channel. The electromagnetic drive includes an armature which acts on a tappet supporting a closing element, which opens or closes the connection channel. At least one pressure spring element acts on the closing element either directly or indirectly in the closing direction. The armature is supported by a core which can adjust the electromagnetic force applied to the armature.

Valve arrangement for pressure regulation of fuel supply in an internal combustion engine

An electropneumatic control valve for regeneration of a fuel absorption element by supply of air to the absorption element includes a valve comprised of a valve seat member (5) and a valve sealing member (4). The valve seat member is displaceable under the action of a pneumatic control section (2B) while the valve sealing member (4) is displaceable under the control of an electromagnetic control section (2A). The operation of the valve members (4, 5), takes place independently of one another by the respective control sections. During strong suction pressures in connector (11), valve seat member (5) is lowered and during the opening stroke of the valve sealing member (4) a minimum opening is provided whereas during low suction pressure at connector (11) the valve seat member (5) is raised and during the opening stroke of the valve sealing member (4) a maximum valve opening is produced. The valve members are slidably and guidably supported in a fixed sleeve (6) provided with calibrated openings (15).
