Abstract
A compressor includes a piston reciprocating in a cylinder bore. The piston draws refrigerant into and discharges refrigerant from a compression chamber, which is formed between the piston and a valve plate. The valve plate has a discharge port connecting the compression chamber to the discharge chamber. A guide passage facilitates the flow of the refrigerant from the compression chamber to the discharge port. The guide passage is defined in the compression chamber when the piston is located at the top dead center position. This decreases pressure losses that would otherwise occur when the piston is near the top dead center position.
