摘要： PROBLEM TO BE SOLVED: To effectively prevent a leakage of carbon dioxide refrigerant gas out of the shaft seal part of a refrigerator compressor, which is caused by changing the refrigerant gas of a refrigerating cycle to the carbon dioxide from fluorocarbon. SOLUTION: A first mechanical seal 3 and a second mechanical seal 4 are installed in a space between an inboard space A and an outboard space B of a refrigerator compressor, and CO2 insoluble or slightly soluble mineral lubricating oil L is filled up in an intermediate chamber C lying between both these seals 3 and 4. Since a part of high pressure CO2 refrigerant gas in the inboard space A is melted in refrigerating machine oil, it is slightly leaked into the intermediate chamber C through the refrigerating machine oil being interposed as a lubricating oil film in a sealed sliding surface 30 of the first mechanical seal 3, but a sealed sliding surface 40 of the second mechanical seal 4 sealing a space between the intermediate chamber C and the outboard space B is lubricated by the mineral lubricating oil L, so that the CO2 refrigerant gas in the intermediate chamber C is checked of its more leakage into the side of the outboard space B. After pressure in the intermediate chamber C is approximately balanced with that in the inboard space A by the leakage of the CO2 refrigerant gas, the leakage of the gas into the intermediate chamber C from the first mechanical seal 3 is also checked as well.

摘要： PROBLEM TO BE SOLVED: To provide an operation axis velocity reduction gear, for which the deceleration urging force is relatively large, even if it is a short distance through entire actuation of a device, and furthermore for which deceleration applied ability is relatively large. SOLUTION: The reduction gear is the operation axis velocity reduction gear 1, which makes the operating axis decelerate by means of a slide having an expanding diameter part by being fitted to the operating axis, which includes a smaller diameter part, as well as the expanding diameter gradually expanding from the end part of the small-diameter part and, includes balls 2 arranged around the small-diameter part of the operation axis, a received part 4 for rotatably holding the balls 2, and simultaneously and movably holding in the radial direction of the operating axis and an elastic holding means 5, which lies outside the balls 2 and which elastically biases toward center of axis of the operating axis by opposing to force, by which the balls 2 are moved in outside diameter direction by the expanding diameter part, and is set to the elastic holding means 5, so that the value of initial pressure on which the balls 2 are moved in the outside diameter direction by the expanding diameter part is opposed.

摘要： PROBLEM TO BE SOLVED: To reduce clearance between the outside diameter of a piston and the inside diameter of a cylinder by providing a circumferentially continuing slit in the head of the piston. SOLUTION: A thermal expansion absorption device 4 has an anchored part 41 anchored to the head 11 of a piston 1 and has a sealing part 42 extended to the outer periphery to dose a slit 15 and freely slidably and elastically brought into close contact with the upper end face 12a of a skirt 12. Thereby combustion gas is prevented from flowing out through the slit 15 and the route of heat radiation from the head 11 to the skirt 12 is secured whereby an expanding force generated by the thermal expansion of the head 11 held at high temperatures can be prevented from being transmitted to the skirt 11 which is relatively low in thermal expansion.
