PROBLEM TO BE SOLVED: To improve abrasion resistance and durability without any complicate link mechanism, and to reduce cost, by rotatably coutacting closely, inserting and connecting a pin into and to a slider rotatably and slidably inserted in a hollow part in which a pin is provided on a lever member by the connection of a motor part and a reciprocating compression part. SOLUTION: A reciprocating compression part and an electric motor part 4 in a closed container 2 are connected to each other by a hollow cylindrical lever member 13. When a crank shaft 10 of the electric motor part is rotated, an eccentric pin B1 is rotated in a slider B2 , the slider B2 is freely slid in the hollow part of an elongated hole B3 of the lever member 13, and the lever member 13 is reciprocated by taking A-1 as the fixed fulcrum. In a connecting part C-1 on the other end of the lever member 13, similarly, the slider C2 is freely slid in the hollow part of the elongated hole C3 of the lever member 13, pistons 11a, 11b connected to the slider C2 are reciprocated by a pin C1 , and refrigerant is sucked, compressed and discharged. The pin, the slider and the lever member are brought in surface-contact with one another, and abrasion resistance and durability are improved. |
