    摘要: A portable, rotary vane vacuum pump (3) with a rotor (13) eccentrically mounted within the bore of a housing (7) to substantially abut the bore at a side location (43). The abutting, side location (43) is between the inlet (31) and outlet (33) passages of the bore in the direction of rotor rotation (21). A pocket (P) is then created just above the contact area (43) between the rotor (13) and bore which collects and maintains a pool of lubricating oil. The pool enhances the seal at the contact area (43) below it enabling the pump (3) to draw a deep vacuum with just a single stage. The portable pump (1) also includes a removable, oil reservoir cartridge (4) mounted to the main body of the pump (1). Other features include a visual indicator (20) in the cartridge (4) to monitor the condition of the circulating oil, a step up gearing arrangement (54) for the cooling fan (50), and a step down gearing arrangement (58) for the vane pump (3).

    摘要: The invention relates to a rotary vacuum pump that has a suction chamber (12) in a housing (10). A rotor (14) is eccentrically mounted in the suction chamber (12). Sliding vanes (18) are connected to the rotor (14). A discharge channel (30) is also connected to the suction chamber (12) and to an oil chamber (32). A valve arrangement (38) is disposed between the discharge channel (30) and the oil chamber (32), in order to prevent the medium from flowing back from the oil chamber (32) into the suction chamber (12). According to the invention, at least one compensating channel (50) is provided and is connected to the discharge channel (30) and to the oil chamber (32).

    摘要: There is provided a scroll type compressor using lubricant oil and including a pair of scroll members (20, 30) confronting with each other in an axial direction. Each of the scroll members has an end plate (22, 32) extending perpendicular to the axial direction and an involute wall (21, 31) having a first and a second axial end which are opposite to each other in the axial direction. The first axial end is connected to the end plate. The second axial end confronts with the end plate of a counterpart one of the scroll members. In the scroll type compressor, the second axial end has a shallow groove (26, 36) with a depth for suitably holding therein the lubricant oil to form an oil seal between the second axial end and the end plate that confronts with the second axial end.
