Abstract
800,830. Hydraulic brakes. DUROUX, J. Feb. 20, 1956 [March 16, 1955], No. 5180/56. Class 103 (1). In an hydraulic brake system for automobile vehicles and the like, a pressure-operated diaphragm switch 1 is located in the master cylinder near to the outlet thereof so that if the liquid pressure falls below a certain value, the diaphragm 2 flattens from the position shown in Fig. 3 and the collar 3<SP>1</SP> on spindle 3 bridges the conducting washers 8 to complete a circuit to operate a warning lamp 14, horn or other indicating device. As shown in Fig. 2, the circuit to the pressure switch 1 includes an indicator J which normally gives warning as to whether the lubrication oil pressure is satisfactory. In another embodiment, Fig. 8, the pressure switch has a double action, and when the master cylinder is operated, the collar 3<SP>1</SP> on the spindle 3 bridges two further conducting washers 12 on terminal 11 to energize a circuit including the vehicle rear warning lights.
