    摘要: A vibrating compressor having a housing with an inner tube and an outer tube formed concentrically. The inner tube is connected with the outer tube via an end plate. The end plate being disposed at one axial end of the inner tube and the outer tube to form a housing closed end and a housing open end. A permanent magnet is fitted to an inner circumferential surface of the outer tube. A driving coil is provided in a gap between the permanent magnet and the inner tube. A cylinder is fitted into an inside of the inner tube and a hollow piston equipped with a valve is inserted into the cylinder. The hollow piston is connected to the driving coil via a bobbin and is supported by support springs in such a manner as to perform reciprocating motion. A cylinder head connected to the housing forms a compression chamber at an end of the cylinder and compressed fluid is discharged from the compression chamber by the reciprocating motion of the piston. First and second cover plates are disposed at opposite ends of the housing to form a sealed container with the housing.
