Abstract

PURPOSE:To prevent malfunction of a vane and incomplete compression at start of a vane type compressor by feeding gas in a high pressure chamber into a vane back pressure chamber when starting under such condition as the differential pressure between high and low pressure sides is low. CONSTITUTION:Upon start of compressor under such condition as the differential pressure between high and low pressure sides is low, vane 4 will spring out to lower the pressure in a vane back pressure chamber 17. Consequently, gaseous fluid is fed through the second gas supply path 33 opening above a high pressure chamber 14 thus to assist spring out of the vane 4. Upon elapse of some interval, the differential pressure between high and low pressure sides will increase where over-compressed gas immediately before the delivery valve 11 of a working chamber 8 will function through a pressure lead-in path 31 to one side of a valve body 29 thus to seat the valve body 29 in a valve seat 30 and to interrupt the first and second gas supply paths 27, 33. Consequently, only high pressure oil is fed through a oil path 18 into the vane back pressure chamber 17.
