<p>644,824. Road and rail vehicle undercarri'ages. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov 6, 1944, No. 4610/48. Convention date, Nov. 6, 1943. Divided out of 644,771. Drawings to Specification. [Classes 103(vi), 108(ii) and 108(iii)] [Also in Group XXIX] A governing device for the control of hydraulic stabilizing apparatus on road or rail vehicles comprises a housing having a low pressure chamber with an outlet conduit for the discharge of liquid and an intermediate pressure chamber communicating with said low pressure chamber, means including at least one high pressure conduit having a first outlet for the supply of liquid under pressure to said intermediate pressure chamber and a second outlet for applying controlled pressure to the apparatus to be controlled at least one byepass valve disposed between said high pressure conduit and said intermediate pressure chamber for controlling the escape of liquid from said high pressure conduit to said intermediate pressure chamber thereby to vary said controlled pressure, flow restricting means forming part of the communication between said intermediate pressure chamber and said low pressure chamber for maintaining the pressure in said intermediate pressure chamber at a value between the pressure in said low pressure chamber and said high pressure conduit, inertia responsive control means biassed normally to maintain a given position but movable therefrom in opposite directions, and means controlled by movement of said inertia responsive control means for actuating said byepass valve so as to vary said controlled pressure in dependance upon the deflection of said inertia-responsive means. The invention is described with reference to the disclosure in Specification 644,771.</p> |
