Abstract: A brake system for a vehicle having a traction control or anti-spin function for controlling wheel slip on differentially driven wheels of a vehicle. The system includes left and right fluid pressure operated brake mechanisms associated with left and right driven wheels of the vehicle. First and second brake valves control the communication of fluid pressure to the left and right brake mechanisms. In normal operation, an operator actuatable treadle concurrently operates both valves to simultaneously apply fluid pressure to the brake mechanisms as a function of treadle depression. Each brake valve includes a pilot pressure operated section for actuating a main fluid control section. Wheel speed sensors associated with the left and right driven wheels continuously monitor the rotational speed of the wheels.

Abstract: A hydraulic pressure cylinder with an integrated reservoir which includes a cylinder body of strengthened resin, a reservoir tank of strengthened resin molded with the cylinder body as one body and having a wall portion and an opening formed in the wall portion of the reservoir tank and having a frame portion defined by the opening, and a window plate formed of resin material soluble in said strengthened resin and having a high transparency characteristic, the window plate including a flange which is welded to an inner surface of a wall portion of a reservoir tank and a projecting part which projects from the flange toward an outer surface of the wall portion of the reservoir tank along the frame portion.

Abstract: The invention comprises a trigger mechanism providing stepwise linear motion responsive to a shaft rotating above a predetermined rate. The trigger mechanism comprises a rotating shaft having a collar thereabout attached to rotate therewith. Also part of the mechanism are a plurality of arcuate cams mounted within the collar to rotate therewith, each biased with the ends of the arcs thereof adjacent the collar at a normal shaft rotation rate of no more than said predetermined rate and the midpoints of the arcs thereof spaced away from the collar towards the shaft. The midpoints of the arcs are forced centrifugally to adjacent the collar when the shaft rotates above said predetermined rate (at overspeed).
