Abstract
926,323. Vacuum brakes. KNORR-BREMSE G.m.b.H. July 20, 1960 [July 21, 1959], No. 25320/60. Class 103 (1). In automatic two-chamber vacuum rail brakes, a quick-action valve 7 for admitting atmosphere into a brake cylinder lower chamber 11 is controlled by a piston 15 acted upon in the valve-opening direction by pressure in train pipe 1 and in the valve-closing direction by pressure in a counteracting control chamber 17 connected to a pipe-line 33 between the valve 7 and the cylinder lower chamber 11 by a union 39 arranged on a section of the pipe-line 33 constructed as an ejector 35. As shown, the brakes are released, regulation vacuum obtaining in all chambers of the system. Increased pressure in the train pipe 1 passing by branch 3 into control chamber 5 lifts the piston 15 to open valve 29, 31 by abutment 27 so that atmosphere enters chamber 25 and hence by the pipe-line 33 into the cylinder lower chamber 11 to apply the brakes. The air flow through the ejector 35 draws air from the control chamber 17 to increase the force of the piston 15, but increased pressure in the cylinder lower chamber 11 decreases the flow so that air penetrates from the chamber 25 to the control chamber 17 causing the piston 15 to descend and closing the valve 29, 31. On admission of regulation vacuum into the train pipe 1, the brakes are released.
