Gas ducting mechanism in a piston compressor

摘要

A piston compressor is described which has pistons which are arranged in bores of a cylinder block and are moved back and forth by a drive mechanism in interaction with a drive shaft. A valve accommodation chamber is formed in the cylinder block around the drive shaft, in order to accommodate a turning valve which corotates with the drive shaft. The turning valve has an intake duct formed therein, to duct gases from a gas intake chamber to a compression chamber formed in each bore. A multiplicity of connection ducts is formed in the cylinder block, assigned to the compression chambers, to provide a gas connection between the compression chambers and the intake duct of the valve. A bypass duct is formed on the turning valve and permits a connection duct assigned to one of the compression chambers, which is in the final stage of a compression stroke, to communicate with a different connection duct which is assigned to a different compression chamber which is in the initial stage of the compression stroke. The compressor further comprises a device which is provided on an external surface of each piston, for collecting gas which leaks in the axial direction along the outer surface of the piston. The gas collection device ducts the gas which it has collected in the final stage of the compression stroke, to the connection duct which ... its associated ... Original abstract incomplete.
