Abstract

369,018. Fluid - pressure brakes. HOUPLAIN, G., 40, Rue Barque, Paris. April 1, 1931, No. 9893. Addition to 363,632. [Class 103 (i).] The orifice 5 by which compressed aid is supplied to the auxiliary cylinder 4 of fluid pressure brake apparatus as described in the parent Specification is provided with a valve 24 which is held open when the piston 3 is in its initial position by the engagement of the rod 25 of the valve with the end of the cylinder 1, but is closed by a spring 27 when the piston 3 moves. When the valve 24 is open compressed air supplied through the port 2 reaches the cylinder 4 through the tubular rod of the valve and orifices in the wall of the rod. The closure of the valve prevents flow of air from the cylinder 4 to the cylinder 1 when the piston 3 moves except through the spring-loaded valve 29 and also prevents the return of the piston 9 until the piston 3 has returned to its initial position.
