Oil level control apparatus

摘要: An apparatus (38) is disclosed for controlling the level of oil in one or more compressors (10) a refrigeration system. The are supplied with from reservoir (28) which fluid communication via common conduit (32) and second (98) sump (not shown) each compressor (10). includes housing composed main body portion spacer block. provided chamber houses float. its respective As within varies, angle pivot float also varies. This variation sensed by sensor produces signal indicative oil. When that below first predetermined minimum level, solenoid valve (78) opened (82) closed. allows (24) to flow conduits (32 98) into compressor. In another embodiment, if higher than maximum caused close open resulting being dumped back (98 32).
