Abstract:
1. A piston compressor comprising: a cylinder housing which forms a cylinder wall that defines a cylinder; a piston which oscillates in the cylinder and, in a filling position, compresses gas in a cylinder pressure space, the piston defining a piston wall which faces the cylinder wall; gas bearing nozzles arranged adjacent the piston for gas-supporting the piston, at least one of the gas bearing nozzles being arranged in the cylinder housing and facing the piston wall; a compressed-gas accumulator connected with the gas bearing nozzles; a compressed-gas supply line between the cylinder pressure space and the compressed-gas accumulator; and an inlet valve in the compressed-gas supply line, the inlet valve being open in the filling position of the piston the inlet valve being defined by a cylinder wall opening and a piston wall opening which, in the filling position of the piston, are located opposite each other and define an open valve, and, in a non-filling position, are closed by the piston wall and the cylinder wall, respectively, and define a closed valve.
