Abstract
A refrigerant compressor is disclosed having pistons that reciprocate in radially arrayed cylinder bores of a cylinder block. A discharge chamber is formed in the compressor. A valving means including a timing plate is positioned within the discharge chamber, and alternately covers and uncovers the compressor outlet port. The timing plate includes spaced variable flow orifices to thereby attenuate the pressure pulsations that occur during the operating cycle. The timing plate is a circular disc rotatably connected to the end of the compressor drive shaft. Each flow orifice is pear-shaped and positioned with a constant radial and circumferential spacing for synchronization with the cylinders.
