Abstract

588,615. Swash-plate pumps. TRIGGS, W. W. (New York Air Brake Co.). Aug. 14, 1944, No. 15476. [Class 102 (i)] In a swash plate pump, the cylinder block 17 is gripped between two parts 11, 12 of the pump housing, a sealing ring 19 being interposed. Each piston 21 has an axial bore 22 and a transverse bore 25 through which inlet takes place when it. is exposed beyond the end of the cylinder; further radial bores 23 connect the bore 22 with grooves 24 for lubricating purposes. Each cylinder is fitted with a delivery valve 26 and delivery takes place through a passage 34 and opening 35 in the housing. The inlet to the housing is through a slot in the boss 42 on the swash plate, and lubricates the radial bearing, that communicates with a radial slot 48 in the swash plate to lubricate the surfaces of the swash plate engaging the thrust bearing 44 and an annular plate 49 against which the pistons bear; more than one annular plate may be provided, The swash plate acts as an impeller to the liquid passing through it to the interior of the housing. Each piston has a partly spherical recess into which is pressed and retained a partly spherical surface of thrust blocks 32 provided with flat faces engaging the annular plate 49.
