ABSTRACT:
A coolant gas guiding mechanism in a compressor is disclosed. A plurality of pistons reciprocate within corresponding cylinder bores that are formed around the rotary shaft, inside a casing. Each piston defines a working chamber in the corresponding cylinder bore. A rotary valve is provided coaxially with a rotary shaft. The rotary shaft has a suction chamber, an inlet through which the coolant gas is sucked in from external coolant circuit, and an outlet which communicates with a selected one of the working chambers in synchrony with the reciprocating movement of the piston, for supplying the coolant gas to the working chamber.
