The invention relates to a multiple valve arrangement for flowing media, such as, air, water or other fluids. In order to produce fluidic valve connections which are complex in as small a space as possible, the valve arrangement comprises a sandwich-type plate structure (12) comprising two external channel plates (13, 15) and a intermediate sealing plate (14) arranged therebetween in addition to a housing (11) surrounding the plate structure (12). Flow channels (16) covered by the sealing plate (14) are formed in the front plate surfaces (131, 151) of the channel plates (13, 15) which are disposed opposite the sealing plate (14) and inlets and an outlets (17, 18) arranged on the rear sides of the channel surfaces (13, 15) are connected to the flow channels (16).

The invention relates to a method for alternatively impinging at least two receptacles (10, 11, 12) of a pneumatic system, particularly a pneumatic massage system of a motor vehicle seat, with a flow of a pressurizing means. At least one inventive first airbag (10, 11, 12) that is used as a receptacle (10, 11, 12) is filled with a gaseous effective fluid while said effective fluid is actively sucked out of at least one additional, second airbag (10, 11, 12). The corresponding pneumatic circuit is configured such that the at least one first receptacle (10, 11, 12) is connected to the at least one second receptacle (10, 11, 12) via joining means (14, 16, 18, 20, 88, 90, 94, 96, 98) and a delivery pump (22). Also disclosed is a vehicle seat, especially a seat for a motor vehicle, which is provided with at least two integrated receptacles (10, 11, 12) that are alternatively impinged upon by a pressurizing flow of the effective fluid according to the inventive method.

The invention relates to a pneumatic control and regulation device (10) for hydraulic fluid flows, comprising an inlet channel (14), two outlet channels (16, 18) and a ventilation channel (20), in addition to a valve piston (90) which is arranged in a valve chamber (92) and which enables communication between said channels. The invention also relates to a method for controlling and regulating hydraulic fluid flows. The respective outlet channels (16, 18) of the pneumatic control and regulation device (10) are simultaneously and alternately connected, according to a pre-determined time constant, with the inlet channel (14) and with the ventilation channel (20), by means of a pneumatically driven valve piston (90).

摘要:
The invention relates to a device with which a positive pressure is at least temporarily generated in a system (S) with respect to an ambient pressure (U). The device further comprises a pump (P) with a pressure side (20) and an intake side (10). When the positive pressure is generated, the pressure side (20) communicates with the system (S) and the intake side (10) communicates with the ambient pressure via at least one valve (MV1), especially a solenoid valve. The inventive device further comprises means that provide an additional cross-section of the intake volume flow when the positive pressure is generated. The invention further relates to a valve that is especially designed for use together with the inventive device.
