Abstract
393,977. Lubricating rotary compressors. NICHOLS, T. W., 63, Capel Road, Forest Gate, London. Dec. 16, 1931, No. 34884. Addition to 331,054, [Class 110 (ii), Rotary engines &c.]. [Class 12 (iii).] In a compressor having an eccentric rotor A having teeth meshing with a revoluble ring B in a casing C, and outwardly sliding vanes D, the oil provided for lubricating the compressor is sprayed into the incoming air entering at E by way of a nozzle S under pressure of the delivery air. The air is delivered by the rotor through two ports G into baffle chambers H and through narrow orifices N where the oil is separated out into traps O leading to the oil sump P, and the air passes on through a passage Q to the outlet F. The pressure of the delivery air acts on and forces down a piston valve U, Fig. 4, so that oil from the sump P is forced up a pipe P<1> to a regulator L, which may be a needle valve, and through a sight glass M to the nozzle S. When the compressor stops, the valve U rises under the action of a spring V and shuts off the oil sump from the pipe P<1>. Cooling water enters a port T and circulates above and below the baffle chamber through compartments R, and leaves at an outlet T<1>. When the machine is to be used as an exhauster, air cooling only may be provided, and a non- return valve X may be fitted at the delivery F, and the valve U dispensed with. Strainers for the oil are provided. Extra oil pipes P<1> may be fitted. Each tooth on the rotor A may be split up into a number of teeth, and each slot in the ring correspondingly split up. The apparatus may be fitted to other types of rotary pumps or compressors.
