Abstract

355,457. Lubricating rotary engines or pumps. UHER ENGINEERING CO., Ltd., Kubli House, Poststrasse, Glarus, Switzerland. July 14, 1930, No. 21345. Convention date, July 13, 1929. [Class 12 (ii).] In a rotary engine or pump having blades 4 sliding in radial slots 5 in a rotor 3 mounted eccentrically in a cylinder 1, lubricant under pressure is supplied through an axial bore 21 and radial ducts 22 in the rotor to the slots and passes into the cylinder intermittently at times controlled by the movement of the blades. The lubricant is supplied to the bore 21 by a pipe 28 connected to the end cover 11, communication between the interior of the cover and the bore being controlled by an adjustable valve 32. A branch 29 from the pipe 28 supplies lubricant to the rotor-shaft bearing 7, the bearing 71 being lubricated directly from the cover 11. The leading faces of the blades 4 are provided with radial grooves 35 extending from the inner edges of the blades but stopping short of the outer edges, whereby lubricant is ejected from the slots 5 through the grooves into the cylinder intermittently. Similar radial grooves may be provided in the ends of the blades for lubricating the endplates 2, 2<1>. Alternatively, end grooves 36, Fig. 2, stopping short of the outer edges and adapted to register intermittently with grooves 37 in the end of the rotor may be provided, the grooves 37 being in communication with the inner ends of the slots 5 ; or the end grooves may be formed as at 361, Fig. 2, so that they also serve to deliver lubricant intermittently into the cylinder. The outer edges of the blades are fitted with cylindrically-seated packing strips 6. The cylinder 1 is provided with a water jacket 18, delivery valves 14, and adjustable relief valves 15, 16 connected by passages 17 to the delivery pipe 70.
