PROBLEM TO BE SOLVED: To reduce a delivery gas temperature of a claw pump by inexpensive means.SOLUTION: A pair of rotors 22a and 22b having hook-shaped claws 24a and 24b are respectively fixed on two rotating shafts 20a and 20b provided in an inside of a housing 12. Delivery ports 26a and 26b are formed on side plates 16a and 16b constituting the housing 12, and partition plates 28a and 28b are fixed on the rotating shaft 20a between the rotor and the side plate 16a or 16b. Openings 30a and 30b are formed at a position opposite by 180° in a circumferential direction on the partition plates 28a and 28b, and an end compression space Pc is alternately communicated with the delivery port 26a or 26b through the opening 30a or 30b during one turn of the rotors 22a and 22b. Accordingly, compressed gas is alternately delivered to the delivery port 26a or 26b. |
