Title: An improved levelling valve for vehicles with pneumatic or hydraulic suspension
Inventor: TREVASKIS HENRY WILLIAM
IPC: B60G17/056
Filed: 1958-11-03
Abstract: 927,274. Adjusting body height from ground. DUNLOP RUBBER CO. Ltd. Oct. 26, 1959 [Nov. 3, 1958], No. 35206/58. Class 108(2). A vehicle levelling valve, operates in response to static load changes but is prevented from responding to dynamic load changes by mechanism activated by suspension movements due to road irregularities. When the load on the vehicle increases, a lever 22 (connected at 26-29 to the vehicle axle) turns to depress the valves 20, 18, and so allow fluid from a supply port 14 to pass to an outlet port 12 leading to the suspension spring (not shown). When the load on the vehicle decreases, the lever 22 turns in a counterclockwise direction to lift the valve 20 and allow fluid to flow from the suspension spring to an exhaust port 16. The connection between linkage 26-29 and the lever 22 comprises a sleeve 30 rigid with the link 26 and a helical spring 33 the legs of the ends of the coils of which pass through slots in the sleeve 30 and bear against opposite faces of the left hand end of the lever 22. When the vehicle is in motion, the sleeve 30 will be continuously oscillating due to suspension movements. As a result, a cam surface 35 on sleeve 30 coacts with a lever 36 pivoted at 37 causing a plunger 39, loaded by a spring 38 to force liquid into a chamber 41 and thence through a non return valve 42 into a chamber 43. The latter is formed by a cylindrical rubber bag 44, supported by a wire coil 45. A latch lever 49 pivoted at 50 is bifurcated at its lower end 51 which is urged into contact with the flange 47 by a weak spring 52. A notched portion 53 of the lever passes thro' a slot 54 in the lever 22 and has a small recess 55 to engage the lever 22. As fluid is pumped into the chamber 43, it forces the member 46 away from the plunger 39. The latch lever 49 follows the flange 47 due to the spring 52 and latches the lever 22 to prevent it from actuating valves 18 and 20. When the vehicle stops, fluid is expelled from the bag 44 through a bleed 56. The flange is then gradually moved to the left sufficiently to displace the latch lever 49 from engagement with the lever 22. If a change in static load occurs, e.g. due to consumption of fuel, the cam surface 35 will no longer be operative with the lever 36 and operation of the plunger 39 will cease. Leakage of fluid through the bleed 56 will release the latch lever 49 and allow the lever 22 to correct the level. When the predetermined level is regained the cam will again become effective and the lever 22 will be relatched.

Each device includes a dose measuring cylinder 3b with a piston 2b, adjustable stop means 6b determining the travel of the piston, a slide valve 10b associated with the piston and having a smaller cross-section than the piston, a cylinder 11b receiving the slide-valve and having its ends communicating each with one end of the dose-measuring cylinder of the next previous device of the series, e.g. via conduits 12, 13, and a delivery conduit leading to a point to be supplied with fluid. The slide valve controls delivery of pressure fluid to one end or the other of the cylinder 3b and the delivery of fluid from the other end of the cylinder to the delivery conduit, e.g. via outlets 18, 19. A control block 1a is provided upstream of the devices 1b, 1c, 1d which serves to operate the slide valves 10b &c. in series.  In one embodiment the control block includes a slide valve 10a and a dosing cylinder 3a. The valve 10a is moved manually, mechanically or electromagnetically to allow fluid from pipe 21 to enter one end of cylinder 3a via conduit 15 thus causing a piston 2a to expel fluid via conduits 14 and 16 to outlet 18. Fluid also passes via conduit 13 to the next slide valve 10b and the sequence of operations is repeated throughout the series of devices. Return of the slide valve 10a causes reverse movement of all the slide valves and dosing pistons of the series. A counter 23 may be operated by a rod 24 attached to the final piston. In other embodiments there is no dosemeasuring cylinder in the control block and this may include a rotary valve. Travel of the pistons is limited by rods 6b, 6c, 6d attached to screw threaded stoppers 9b, 9c, 9d respectively.
