Abstract

PURPOSE:To improve the extent of compression efficiency by opening or closing an oil feed passage between an oil sump and an inlet chamber by means of a check valve gear in the midway of an injection passage lying between a discharge chamber and a compression space. CONSTITUTION:An interval between a first compression space 39b and an oil sump 18 is interconnected by an injection passage consisting of an oil suction hole, a non-return valve gear 17, a punched groove 45 and an injection hole 30b. An interval between the oil sump 18 and an inlet chamber 33 comes to a lubrication passage leading to bearing 49, 51 by way of an oil hole 46. A reed valve 53 of the non-return valve gear 17 and a reed valve 54 of a check valve 16 both are formed after punching a part of a valve plate. Consequently, the non-return valve gear comes to double as an on-off valve for the oil feed passage, thus space saving is well promotable.
