Title: Cooling device of open-type refrigerant compressor
Inventor: FUJIO KATSUHARU
IPC: F04B39/06
Filed: 1982-11-19
Abstract: PURPOSE:To prevent the deterioration of the seal performance of a shaft seal device by endothermically cooling the refrigerator oil of a high temperature fed through a main oil feed passage and cooling the shaft seal device simultaneously by means of the compressor load detection with a sensor and the switching of an auxiliary oil feed passage. CONSTITUTION:When the refrigerant temperature on the discharge side exceeds a preset value, the circuit of a three-way valve 30 is switched so that the second auxiliary oil feed passage is opened and the first auxiliary oil feed passage is closed by a command of a sensor 32. Therefore, a liquefied refrigerant passes through a capillary tube 31, the low-temperature refrigerant gas in a non-endothermic status flows into a shaft seal device space 10 and joins with the refrigerator oil of a high temperature fed into the shaft seal device space 10 through a main oil feed passage 29, thus reducing the refrigerator oil temperature, thereby the seal performance of the shaft seal device can be prevented from deteriorating.
