Open the CIPO recordAbstract From the Canadian patent
Accelerator for an indirectly operating air brake The accelerator of an indirectly operating air brake has a bleed valve (30) which vents the main air line at the start of the braking operation. This bleed valve (30) is opened by an actuating member (1) by means of an unlatchable intermediate link (10). The design of an intermediate link can be greatly simplified by the use of a rotationally symmetrical tappet (10) which is swivelled into its operational position by a spring (11) and out of said operational position by a breaker piston (16). At one end this tappet (10) has a cam (13) and a conical surface (15). (Fig. 1)
