Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A precompression control arrangement for the supply of fuel from a fuel pump arranged in a fuel tank to a fuel line and then to a fuel distributer of an internal combustion engine. A pressure-regulating valve is arranged in the fuel tank, which diverts fuel from the fuel line when the valve is opened and returns the fuel to the fuel tank. The pressure-regulating valve has first and second chambers, separated in a liquid-tight manner by a membrane which actuates a valve closing member. The first chamber has at least one inlet, connected to the fuel line by a first branch line, and at least one outlet, which leads into the fuel tank. The second chamber has a spring which biasses the valve closing member in the closing direction. The second chamber has a second inlet, which is connected to the fuel line by a second branch line which incorporates a switch such that different pressure levels can be adjusted in the second chamber.

Abstract: A pressure-regulating apparatus for supply of fuel from a fuel pump in a fuel tank via a fuel line to a distributor of an internal combustion engine, a pressure-regulating valve being arranged in the fuel tank, to return fuel from the fuel line, when the valve is opened, to the fuel tank. The pressure-regulating valve has first and second chambers separated in a liquid-tight manner by a membrane which actuates a valve-closing member. The first chamber has at least one inlet connected to the fuel line by a first branch line and at least one outlet which leads into the fuel tank. The second chamber contains a spring which biasses the valve-closing member to a closed position. The second chamber of the pressure-regulating valve has a second inlet connected to the fuel line via a second branch line, and a switch device in is provided the second branch line to establish different pressure levels in the second chamber.

Abstract: 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).
