Abstract

798,941. Fluid-pressure brakes. KNORRBREMSE GES. June 22, 1956 [June 23, 1955], No. 19497/56. Class 103 (1). In a fluid pressure brake system of the kind comprising a main air line 1, a triple valve 3 and reservoir 33, and in which the pressure operative in a cylinder 41 is varied in accordance with the load applied to the vehicle by the movement, through pivotal lever 85, 87 of a fulcrum block 63 so as to adjust the coupling between the piston rod 13 of a control piston 11 and the piston rod 17 of a return piston 21, a second brake cylinder 47 is brought into operation if the load on the vehicle should be such as to cause stop 77 on rod 65 to strike lever arm 79 and open valve 45. Simultaneously the arm 71 of a lock member 67 is arranged to strike block 73 so as to release the fulcrum block 63, which is then pulled upwards by spring 69 into engagement with a stop 75 on the rod 65. The fulcrum 63 then acts to vary the leverage between pistons 11 and 27 in the same manner with both cylinders 41 and 47 in operation as it had done when only cylinder 41 was operative. In another embodiment described, the pressure transmitter unit is omitted and the block 63 is adjustable along a rod corresponding to rod 53.
