本発明は冷凍サイクルに使用する冷媒圧縮機に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerant compressor used in a refrigeration cycle.
従来の密閉型の冷媒圧縮機は、潤滑油の粘度が
高いと機械部の摩耗が著しくなり冷媒圧縮機の寿
命に影響を与えるものであつた。 In conventional hermetic refrigerant compressors, when the viscosity of the lubricating oil is high, the mechanical parts suffer significant wear, which affects the life of the refrigerant compressor.
本発明は上記点を考慮した冷媒圧縮機を提供す
るものである。 The present invention provides a refrigerant compressor that takes the above points into consideration.
以下図面により本発明の一実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.

4 is an electric motor. 5 is a compression mechanism, 6 is a cylinder, 7 is a piston, 8 is a valve plate, and 9 is a discharge muffler. Reference numerals 10 and 11 denote a pair of discharge pipes that guide the compressed gas in the discharge muffler 9 to the discharge ports 3 and 3'.

壁に取付けられた熱応動型プロテクタである。 One discharge pipe 10 passes through the lubricating oil 12 and is piped to the discharge port 3, and the other discharge pipe 11 passes through the upper air inside the casing 1 and is once led out to the outside, and then carries out the lubricating oil 12. It is piped through the discharge port 3'. 13 is a switching valve provided at the branch part of both the discharge pipes 10 and 11;
The switching is performed by a bimetal thermostat 14 provided outside the casing 1 to detect the outside air temperature. The refrigerant gas that has passed through the discharge ports 3 and 3' both flows into the condenser 15, passes through the capillary tube 16 and the evaporator 17, and returns to the suction port 2. 18 is a thermally responsive protector attached to the outer wall of the casing 1.

２の粘度が高くなつて機械部の摩耗を少なくする
ものである。 In such a device, when the outside temperature is high, the switching valve 13 directs the discharge gas to the discharge pipe 1.
The temperature of the discharged gas is lowered outside the casing 1 and then returned to the lubricating oil 12 to prevent the temperature of the lubricating oil 12 from rising. Furthermore, when the outside air temperature is low, the switching valve 13 is activated and the discharged gas flows into the condenser 15 through the discharge pipe 10 side. In other words, when the outside temperature is low, the lubricating oil 12 is warmed by the temperature of the discharged gas, so the lubricating oil 1
The viscosity of No. 2 increases, which reduces wear on mechanical parts.
上記実施例より明らかなように、本発明は外気

る不都合を防止するものである。 As is clear from the above embodiments, the present invention controls the outflow direction of the discharged gas using a switching valve that switches the outflow direction depending on the outside temperature. The viscosity of the lubricating oil is increased to reduce wear on mechanical parts, and the other direction of outflow is the discharge pipe. After the lubricating oil has been drained, it passes through the lubricating oil again to lower the temperature of the lubricating oil, thereby preventing problems caused by the lubricating oil becoming abnormally high temperature.
