Abstract: 1,259,623. Swash-plate pump. BORGWARNER CORP. March 18, 1969 [April 16, 1968], No.14291/69. Heading F1A. In order to vary the stroke of a swash-plate type piston pump 10, the swash-plate is formed from two parts 29, 30 the first of which is rockably keyed to the drive-shaft 35 and through slippers 24 co-operates with the pistons 16, the second part 30 being rotatable relative to the first part 29 on reversal of the drive-shaft 35, the relative rotation being controlled by a one-way spring clutch 40 wrapped around the periphery of part 30 and anchored to the pump housing and an escapement mechanism 42 operatively connected to the driveshaft 35 and part 30. The pistons 16 are mounted in cylinder bores 15 in a cylinder block 13 and biased towards the swash-plate 29, 30 by springs 25, and spring-loaded ball-valves 19, 48 are mounted in piston inlets 18 and cylinder outlets 49 respectively.

Fuel is supplied to that part of the member 23, 24 which is first shielded through an orifice 21 and fuel may be supplied to the part 24, separated from the part 23 of greater porosity by a metal strip 25, through an orifice 20. Fuel may be supplied to the orifices 20, 21 from a float chamber providing a fuel level at or below the orifice outlets. The porous member may be formed of a naturally occurring material, e.g. sponge or pumice, but is preferably of an artificially produced material, e.g. a solidified foamed liquid or molten material such as a polyurethane, metal or metallized foam. The porous member may comprise a packed mass of a particulate or fibrous material, e.g. glass beads, powdered alumina, glass or metal wool or polymeric fibrous material such as nylon. The packed mass may be bonded into a selfsupporting structure by sintering or with an adhesive. Polymeric fibres having an outer skin of low-melting point polymer may be bonded together at their intersection points by moderate heating without softening the bulk of material. The porous material may be reinforced by incorporating metal wires or mesh, particularly at the downstream surface. The body and shutter of the carburetter may be formed of metal or plastics. In another embodiment, Figs. 1 and 2 (not shown), a horizontal cylindrical tube (10) of poly (4-methypentene-1) contains a block (11) of foamed flexible polyurethane bonded to it with epoxy resin and a plate (13) of poly(4- methypentene-1) is movable downwardly into the tube adjacent the downstream surface of the block. Fuel is supplied to the top of the block (11) through an adjustable needle valve from a float chamber. The shutter may comprise one or more generally laminar members adapted to slide or rotate in the plane of movement, an iris diaphragm or a cam-like rotatable slide.

Filed: 1971-03-25
Abstract: 1324893 Change-speed control TATRA NARODNI PODNIK 25 March 1971 7839/71 Heading F2D The supply of fluid pressure to apply and release chambers 21, 23, for both applying and releasing a ratio-establishing band brake 25 in an automatic transmission, is controlled by an anchor valve 9, actuated by the reversal of torque reaction which occurs at the anchor end of the brake band during gear-shift. In the band-released neutral position shown, line pressure 6 is fed through the anchor valve 9 to lines 12, 16, the former leading directly to the brake release chamber 23, the latter, 16, to the apply chamber 21 through a neutral valve 40, which, in the neutral position shown, is pressurized at 44 to block the line 16 and exhaust the brake apply chamber 21. Exhausting neutral pressure 44 permits pressure 16 to reach the brake-apply chamber 21, whereupon the brake is applied lightly by a spring 22. In installations in which the brake may remain applied in neutral the neutral valve 40 is omitted. When the brake is required to be applied fully to establish its ratio, forward torque reaction, when it appears, acts rightwards to thrust an anchor pin 1 against a stop 33, whereupon a spring 3 slides the anchor valve 9 along the pin 1 to a stop shoulder 38, to exhaust the release line 12, causing full application of the brake. When an upshift is to be established, a pressure signal 17 acts in an end-chamber 28 to thrust the anchor valve 9 left against a stop shoulder 37 on the anchor pin 1, whereupon both apply and release lines 16, 12 are again pressurized leaving the brake lightly applied by its spring 22. On torque reversal the anchor pin 1, and with it the anchor valve 9 are moved by a spring 10 leftwards against a stop 2, which exhausts the apply line 16 causing the brake to be fully released by release pressure 12. Similar action, in the opposite direction, occurs when the pressure signal 17 vanishes for downshift.
