Abstract: The invention relates to a valve block (10) for use in supplying cleaning medium to a plurality of consumers. The invention further relates to a method for supplying cleaning medium and to a use of a valve block (10). The valve block (10) according to the invention comprises at least one cleaning medium supply connection (22), a plurality of switching valves (24, 26) connected to the at least one cleaning medium supply connection (22), a control unit (14) which is configured to control the switching valves (24, 26) in an alternating manner individually and/or several of the switching valves (24, 26) simultaneously, and a position detection unit which is configured to determine the switching position of at least one switching valve (24, 26) without a sensor.

Abstract: A pneumatic control and measuring device and seat comfort system with such a device. The pneumatic control and measuring device includes a valve and a pressure sensor, wherein the valve includes an input channel, a pressure channel, an output channel and a sealing element switched or switchable by an actuator. The sealing element is configured to connect the input channel with the pressure channel in that a supply pressure provided in the compressed air supply channel is or can be provided at an output connection of the valve fluidically communicating with the pressure channel. A pressure sensor for capturing a pressure present at the output connection is a printed-circuit-board-integrated pressure sensor.
