Abstract (en)
[origin: EP0887550A1] A housing (11, 12, 13) houses a compression mechanism. A driving shaft (15) is supported by the housing (11, 12, 13) and is connected to the compression mechanism. A boss (16) is provided on the external wall of the housing (11, 12, 13) so as to surround the portion of the driving shaft (15) which projects from the housing (11, 12, 13). A rotor (18) is connected to the driving shaft (15) and transmits the power of an external driving source to the driving shaft (15). A shaft sealing device (17) is disposed in the housing (11, 12, 13) and seals the gap between the driving shaft (15) and the inner circumferential surface of the housing (11, 12, 13). A recovery unit (35, 36, 38) is provided for recovering a leakage oil which leaks from the shaft sealing device (17). A stepped portion (40) is formed to extend around the periphery of a rotating portion (15, 21 alpha ) which is positioned on the side of an opening (16 alpha ) of the boss (16) with respect to the shaft sealing device (17) in the housing (11, 12, 13). The stepped portion (40) is disposed opposite to the recovery unit (35, 36, 38). <IMAGE>
