機。 A rotary piston 12 is provided eccentrically within the cylinder 11, and a side cover 13 has side surfaces of the rotary piston 12 in sliding contact with both sides of the cylinder 11.
a, 13b are provided, and the cylinder 1
1, a blade 15 is provided in the cylinder 11 so as to be freely protrusive and retractable, and the tip of the blade 15 is pressed against the rotary piston 12 to form a compression chamber 19 in the cylinder 11. Outlets 17 are opened on both sides of the blade 15 to communicate with the compression chamber 19, while injection passages 27 for cooling oil 22 are bored in the side covers 13a and 13b to connect the inside and outside of the cylinder 11. The inner end outlet 29 of the injection path 27 is unclosed by the rotary piston 12 in a predetermined section in which the rotary piston 12, which forms the compression chamber 19 in an intermediate compression state, rotates by a certain angle from a predetermined position. A supply pipe 26 for cooling oil 22 is connected to the outer end inlet 28 so as to open into the compression chamber 19.
, 32 are connected to each other, and the outlet port 29 of the injection path 27 is opened and closed as the rotary piston 12 rotates.
