Abstract

PURPOSE: To remarkably reduce a frictional resistance of a plunger and a packing and economize a driving power by regulating a pressure of a lubricating oil in an oil groove annularly formed inside a cylinder to balance with a pressure of the oil inside a cylinder.
CONSTITUTION: An oil ring 7 inside a cylinder 4 is disposed in the vicinity to a grand packing 9 and pushed by a packing grand 9' towards the packing 9. An oil groove 8 is formed in the external periphery of the ring 7 and another groove is formed in the side. An oil seal packing 8' is secured in the side groove. In association with the turning of a crankshaft 6, a plunger 5 reciprocates to open or close a suction valve 29 or a discharge valve 35 so as to feed or drain an oil into or from the cylinder 4. An oil in an oil tank 22 is sucked through an oil path 21 into an oil supply hole 17 and then flows through the oil path 18 into the oil groove 8. With the oil path 18 and the oil groove 8 filled with the oil for lubricating, a boosted pressure of a liquid inside the cylinder 4 is trasmitted through a diaphram 14 to the oil in the groove 8, 10 so that the pressure of the oil in the groove 8 balances wit that of the liquid inside the cylinder 4.
