ABSTRACT:
The compressor head, internal and/or external discriminator, and manifold design in general utilize ball valves on the suction and discharge of a cylinder head in the recovery of refrigerant liquid and/or vapor. The device facilitates the flashing of liquid refrigerant pumped to the compressor which, in turn, assists to cool the compressor head. The flashing of liquid refrigerant to vapor also deters liquid transfer into the compressor enhancing performance thereof. The vapor passages within the discriminator, cylinder head and/or manifold are sized for receipt of spring actuated ball's to open and/or close the vapor passages during suction and/or discharge of refrigerant vapor or liquid by the compressor.
