Abstract

1,001,087. Rotary pumps and motors. AIM PUMP CORPORATION. March 1, 1962 [Oct. 10, 1961], No. 8069/62. Heading F1F. A rotary pump or motor of the outwardly sliding abutment type, described as a two-stage compressor, comprises a housing 11, Fig.1, formed by cylindrical parts 12, 13, end covers 15, 16 and a divider wall 14 to form cylindrical chambers 33, Fig. 2, through which passes a concentric shaft 17 driven by a pulley 83 to which is secured a cooling fan 85. On the shaft 17 are eccentrically mounted rotors 21, 22, one in each chamber, with their eccentricities 180 degrees with respect to each other. Each rotor is formed with lightening holes 52, and to reduce the off-centre weight of the rotors, an axially extending recess 38, housing a wiper bar 37, Fig. 3, urged by a leaf-spring 39 into sliding contact with the chamber wall 32 and on its end faces 44 with recesses mounting flexible seal rings 43 which are split to straddle the wiper bar. To provide a proper sliding fit for the bar 37, a resilient strip 40 and a metal strip 41 are fitted in the recess 38 at its leading edge. The outwardly sliding abutment comprises a blade 23 guided at its ends in grooves 26, 27 in an end cover and the divider wall and passing with clearance through a slot 35 into a cavity 34 to which pressure fluid at regulated pressure is supplied through a line 78. The pressure fluid acts on sealing plugs 54, 55 mounted in a bore 53 intersecting the slot 35 to urge the blade 23 into contact with its rotor. The plugs 54, 55 each have a flat surface, the one on the plug 54 being exposed to pressure on the high pressure side of the blade 23 and the one on the plug 55 to pressure in the cavity 34 so that the plug 54 is urged outwardly and the plug 55 inwardly. With the build-up in pressure on the high pressure side of the blade 23, the blade is urged outwardly against a spring-loaded plunger 65 just before the bar 37 passes the slot 35 to be free from contact from the bar to be again urged into contact with the rotor by the spring-loaded plunger 65, 72 immediately the bar passes the slot. An air cleaner 86 is fitted on the inlet connection 87 to the first stage, and an intercooler between the stages. Lubrication oil admitted to the chambers 33 through pipes 98 is afterwards separated from the compressed air. Lubricating oil for the bearings is admitted through pipes 99. In a modification, a rocker assembly 110, Fig. 11, having rollers 117 resiliently loaded by springs 113 co-ordinates the movements of the rotors of the two stages. The driving pulley 83 may be counterweighted to balance the off-centre load of the rotors.
