Abstract: The invention relates to a device for at least intermittently generating an overpressure in a system S in relation to an ambient pressure U, with a pump P that has a pressure side 20 and an intake side 10, where during the generation of an overpressure, the pressure side 20 is connected to the system S and the intake side 10 is connected to the ambient pressure by means of at least one first valve MV1, in particular a solenoid valve. According to the invention, means are provided, which can provide an additional cross section for the intake volume flow during the generation of an overpressure. The invention also relates to a valve, which is particularly provided for use with the device according to the invention.

Abstract: The invention relates to a pneumatic open- and closed-loop control apparatus (10) for flows of pressure fluid, having one inlet conduit (14), two outlet conduits (16, 18), and one venting conduit (20), and also having a valve piston (90) mediating between these conduits and mounted in a valve chamber (92), and to a method for open- and closed-loop control of flows of pressure fluid. It is proposed that by means of a pneumatically driven valve piston (92), with a predeterminable time constant, one outlet conduit (16, 18) each of the pneumatic open- and closed-loop control apparatus (10) is connected to the single inlet conduit (14), while the other outlet conduit is simultaneously connected to the venting conduit (20).

Abstract: The invention relates to a method to act upon at least two recipients (10, 11, 12) of a pneumatic system in an alternating manner, in particular a pneumatic massage system of a motor vehicle seat, with a pressure medium flow. It is proposed in accordance with the invention that at least one, first air cushion (10, 11, 12) that serves as a recipient (10, 11, 12) be filled with a gaseous working fluid, while the working fluid is actively suctioned off from at least one other, second air cushion (10, 11, 12). The corresponding pneumatic circuit is connected in such a way that the at least one, first recipient (10, 11, 12) is connected to the at least one, second recipient (10, 11, 12) via connecting means (14, 16, 18, 20, 88, 90, 94, 96, 98) and a feed pump (22).

Abstract: The invention relates to an electromagnetically actuatable valve that has a magnet part, a moveable armature element, a spring element, and a valve part. The magnet part has at least one coil form with a magnetic coil wound on it, a flux concentrating element and a center pole. The valve part has a closing element that cooperates with the armature element and controls the opening and closing of the valve on a valve seat. The armature element is designed as a clapper-type armature and cooperates with the center pole by way of a damping element.

At least one additional valve (ZV) is provided, which is connected in parallel to the first valve MV1 and can provide an additional cross section for the intake volume flow during the generation of an overpressure.

Abstract: In order to produce very complex fluidic connections of valves in an extremely small amount of space, a multivalve unit for flowing media such as air, water, or another fluid, has a sandwich-like plate structure (12) composed of two outer conduit plates (13, 15) and a central sealing plate (14) situated between them, as well as a housing (11) enclosing the plate structure (12). Front plate surfaces (131, 151) of the conduit plates (13, 15) oriented toward the sealing plate (14) are provided with flow conduits (16) that are covered by the sealing plate (14), and the back plate surfaces (132, 152) of the conduit plates (13, 15) are provided with inlet and outlet openings (17, 18) that communicate with flow conduits (16) (FIG. 1).

Abstract: A pressure level monitoring device includes a housing (10) and a switching unit (12) that is embodied on the housing (10) and protrudes into the inside of the housing. A first membrane (14) divides a first inner housing chamber (44), which can be acted on by pressurized fluid, from a second inner housing chamber (46). The housing is comprised of a top housing part (18) and a bottom housing part (50). A check valve (54) is connected to the first inner housing chamber (44) and is integrated into the bottom housing part (50).
