Title: Improvements in and relating to air pressure regulation in pneumatic tyres of motor vehicles
IPC: B60C23/00
Filed: 1959-05-15
Abstract: 893,638. Controlling tyre pressures. TATRA, NARODNI PODNIK. May 15, 1959 [June 14, 1958], No. 16806/59. Class 144 (2). The tyre pressures of a vehicle are controlled by electro-pneumatic valves 4-7 which each control the supply of air to and from one of the tyres, and by two electro-pneumatic valves 2, 3 which respectively control the supply of compressed air from a supply source (not shown) to the pairs of valves 4, 5, and 6, 7 associated with the front and rear tyres, each valve 2-7 being electrically controlled by an associated switch 19, 22, 18, 20, 21 and 23, whereby appropriate operation of the switches effects inflation, deflation, or pressure equalization of either or both the front and rear pairs of tyres, or deflation of any individual tyre. As shown, each valve 2-7 is a three-way valve with one way connected to atmosphere. In the " open " or switch-actuated position of valves 4-7, each said valve connects the tyre via a rotary joint 46 and the relevant pipe-line 32, 31, 38 or 39 with an associated pipe-line 30, 29, 36 or 37 leading to the relevant valves 2, 3. In the " closed " position (switch open) of said valves the tyre lines 32, 31, 38, 39 are sealed and the lines 30, 29, 36 and 37 are connected to atmosphere through said valves. Likewise the valves 2, 3 in their " open " position connect the compressed air supply via pipes 12, 27 and 28 with the lines 59 and 35 which lead respectively to the lines 29, 30 and 36, 37. In the " closed position of valves 2 and 3, the main supply lines 27, 28 are sealed and the outlet lines 59 and 35 leading to the valves 4-7 are opened to atmosphere at the valves 2, 3. Each valve 2-7 has a push-button 9, 56, 8, 54, 57 and 10, respectively, for manual operation of the valve in the event of electrical failure. The compressed air supply is associated with a reducing valve (not shown) and each tyre supply line 31, 32, 38, 39 is connected to an associated pressure-gauge, the gauges being grouped in front and rear pairs 16, 15. Operation.-Inflation of the front or rear pairs of tyres separately or simultaneously is effected by opening of the associated valve 2, 3 and the relevant valves 4-7 until the required pressure is indicated on the gauges. Deflation of any of the tyres is effected by opening only the desired valve 4-7 whereby the tyre is vented to atmosphere through the closed relevant valve 2, 3. For pressure equalization between the pairs of tyres the relevant valves 2-7 are opened to place the desired tyres in communication with each other. Rotary joint.-Each rotary joint 46 comprises a cover 61 rotating with the wheel and communicating via a pipe 58 with the associated tyre, the cover 61 having a washer 65 against which a sealing washer 66 is pressed by means of a bellows 67. The bellows 67 is carried by a plug 63 through which extends the associated pipe-line 31, 32 or 38, 39, and when said line is pressurized the pressure air acts on the bellows to augment the loading of the sealing washer 66.
