Abstract
1,038,197. Fluid-pressure brakes. V. ZUPANCIC. April 19, 1963 [April 21, 1962], No. 15592/63. Heading F2F. In a braking system for a tractor-trailer vehicle, tractor brakes 2 are operated mechanically by a shaft 1 connected by a crank 3 and link 4 to a pedal 5, and the trailer brakes 25 are operated by an hydraulic cylinder 17 acting on a brake shaft 24, hydraulic fluid being supplied to cylinder 17 simultaneously with the application of the tractor brakes through a slide valve 11 arranged in an hydraulic system comprising a pump 7, an accumulator having a compressedair bladder 13, and a reservoir 20 for the return of fluid to the pump. The slide valve 11 comprises a double piston, a piston-rod of which is connected to a crank 9 on the shaft 1, while a further rod 8 is connected to the crank 9 and also to a control arm 6 for controlling the output of the pump. In operation, the piston of the valve 11 takes up the position shown on application of the tractor brakes, and the control arm 6 is then in position to open the delivery outlet of the pump to supply fluid via the accumulator, which has a non-return valve 14, to the valve 11 and thence via coupling 18 incorporating a non-return valve to the cylinder 17. On release of the tractor brakes the piston of valve 11 moves to shut off the connection between the accumulator and the cylinder 17 and to connect the latter to the reservoir 20. A manual shut-off valve 15 is provided, so that the pump 7 can be used for other purposes, and a pressure-limiting valve 22 by-passes fluid from the pump outlet to the reservoir to regulate pressure in the system.
