Abstract
A compressor has a first housing, a second housing, a valve plate, a suction valve, a discharge valve and a sealing coat. The first housing includes a compression chamber. The second housing includes a suction chamber and a discharge chamber. The valve plate is interposed between the first housing and the second housing. The suction valve is disposed between the first housing and the valve plate. The discharge valve is disposed between the second housing and the valve plate. The valve plate forms a suction port intercommunicating the suction chamber and the compression chamber, and a discharge port intercommunicating the discharge chamber and the compression chamber. The sealing coat made of soft metal is provided between the suction valve and the valve plate, and/or between the discharge valve and the valve plate.
