Abstract

PURPOSE:To operate a duplex head type piston smoothly and contrive to enhance the compression efficiency by providing a needle bearing (which provides rolling friction) at least one of the part between a crank pin and a slider and the part between the slider and the duplex head type piston. CONSTITUTION:The crank pin 2 is engaged with the slider 3 through a pair of needle bearings 11a, 11b, and the slider 3 is engaged to a center hole of the duplex head type piston through needle bearings 10a, 10b. The needle bearings 10a, 10b, 11a, 11b having a diameter of 2.5-3mm. provide rolling friction, thereby largely reducing the coefficient of friction between the crank pin 2 and the slider 3 and that between the slider 3 and the piston 4. Accordingly, the piston 4 can be operated smoothly, the reliability of a driving mechanism of the piston can be enhanced and the compression efficiency for a coolant can be enhanced.
