Filed: 1942-12-09
Abstract: 564,097. Hydraulic master-cylinders. BENDIX AVIATION CORPORATION. Dec. 9, 1942, No. 17549. Convention date, Feb. 2, 1942. [Class 103 (i)] In a two-stage hydraulic master cylinder for the operation of brakes and the like and of the kind comprising high and low pressure pistons of different diameter and a pressure relief valve whereby the low pressure piston is rendered ineffective when a certain pressure has been reached, the relief valve is arranged to close on to a second seat after leaving its normal seat, in the event of sudden operation of the master cylinder. As shown, the cylinder comprises low and high pressure pistons 20, 22 connected by a rod 25 and operated by a pedal through a rod 24. The chamber 27 is connected at 29 to the pipe-lines leading to the brake cylinders and normally to the reservoir 17 through the port 30. The relief valve comprises a ball 34 that has only slight movement between two seats 35, 36, and is normally urged against the seat 35 by a spring 37 to close the communication between the low pressure chamber 28 and the reservoir. When the pistons are operated, liquid is forced by the piston 20 from the chamber 28 past a non-return valve 32 through the passage 31 to the chamber 27 and the brake cylinders. When the pressure rises, as the brake shoes reach the drums, the valve 34 opens and liquid escapes from the chamber 28 to the reservoir. A sudden operation of the master cylinder may cause the valve 34 to leave the seat 35 simultaneously with the opening of the valve 32, but in this event the valve 34 will seat at 36 and thus prevent loss of liquid to the reservoir until the brake shoes are applied.. When upon release of the pedal pressure the pistons are returned, liquid returns to chamber 28 from reservoir 17 through a further passage (not shown) provided with a non-return valve, and if a vacuum tends to form in chamber 27 liquid flows into it from chamber 28 through passage 31.
