Abstract: A compressor and a multi stack fuel cell are provided with adjustable pressurized fluid inputs. A compressor has a first compressor stage that is configured to take in an intake fluid, compress the intake fluid to a compressed fluid and output the compressed fluid as an output fluid at a first pressure. The compressor further has a second compressor stage that is configured to take in an intake fluid, compress the intake fluid to a compressed fluid, and output the compressed fluid as an output fluid at a second pressure.

Abstract: A piston compressor has a piston guided in a compressor cylinder, wherein the piston and the compressor cylinder form a compressor chamber for compressing a fluid. A shaft is provided that rotates around its axis. A lifting element is arranged eccentrically to the axis of the shaft and is provided fixed to the shaft. The lifting element and the piston are configured in such way that the piston performs a movement between a maximum and a minimum lifting position when the shaft rotates around its axis.

Abstract: A module for generating and supplying a control pressure for a pressure-controlled fluidic brake system of a first vehicle, the module comprising a valve unit comprising at least two stable switching states; a pressure source configured to provide a supply pressure to the valve unit; and an outlet port configured to supply the control pressure to the brake system of the first vehicle; wherein the module is configured to generate the control pressure from the supply pressure according to at least two operating modes which are respectively activated according to one of the at least two switching states of the valve unit; wherein the module is configured to set the generated control pressure according to a second of the at least two operating modes to a constant control pressure value to activate the brake system of the first vehicle to hold the first vehicle in at least one of a non-moving state and a parking state.

Abstract: An air supply system for a fuel cell unit and a pneumatic system includes: a fuel cell compressor which is designed to induct air from its intake side and by way of its outlet side convey said air to a fuel cell outlet of the air supply system, the fuel cell outlet being able to be connected to a fuel cell unit; a pneumatic system compressor which is designed to induct air from its intake side and by way of its outlet side convey the air to a pneumatic system outlet of the air supply system, the pneumatic system outlet being able to be connected to a pneumatic system; an intake opening; a fuel cell intake line which connects the intake side of the fuel cell compressor to the intake opening; and a pneumatic system intake line which connects the intake side of the pneumatic system compressor to the intake opening. The fuel cell compressor and the pneumatic system compressor can induct air by way of the intake opening.
