Patent ID: 7004729

Claim:
A compressor with intake and discharge chambers for a suction pressure zone and a discharge pressure zone, the compressor comprising: a pot-shaped housing; a housing sealing cover, the housing sealing cover being a housing cover or a sealing plate; a drive shaft including bearings; a drive mechanism for reciprocating pistons and converting the rotational movement of the drive shaft into a reciprocating movement of the pistons; a cylinder block for aspirating and compressing a coolant through the reciprocating movement of the pistons; a valve device; and a cylinder head, the cylinder head at least partially forming intake and discharge chambers for the coolant aspirated and compressed by the pistons, all of the intake and discharge chambers for the coolant being located on a same side of the cylinder block and within a space defined by the housing and housing sealing cover; the cylinder head being a separate element from the housing or the housing sealing cover, where the cylinder head is radially enclosed by the pot-shaped housing or the housing sealing cover, the pot-shaped housing contacts the housing sealing cover, and the housing sealing cover or the housing being substantially elastic to permit thermal axial expansion of the cylinder head.
