Title: Electromechanical Driver for Hydraulic Valve and the like
IPC: F15B13/043
Filed: 1968-08-14
Abstract: 1,192,689. Electromechanical actuators. ABEX CORP. 14 Aug., 1968 [15 Sept., 1967], No. 38892/68. Heading H1P. [Also in Division G3] An electromechanical transducer comprises a magnetic circuit having an air gap and an armature arranged for substantially rectilinear motion within the air gap in a direction substantially normal to the lines of magnetic flux in the gap. As shown, Fig. 1, an hydraulic jet pipe valve comprises a pair of transducers 24A, 24B actuating a common armature 18 which is mounted on a resilient jet pipe 20. Each transducer comprises a soft iron core 27 carrying a coil 26 and having pole members 29, 30 defining an air gap 28. When the coil is energized the armature is drawn further into the air gap to reduce the reluctance of the gap. The transducers may be provided with bias windings and different modes of energizing the windings of the two transducers are discussed. The pipe 20 directs a jet of hydraulic fluid towards two receiver ports 22A, 22B so that a pressure differential is obtained when a control signal is applied to the coils. The nozzle 34 of the jet pipe and the receiver ports 22A and 22B are surrounded by an annular baffle 40 which protects the armature and air gaps from the hydraulic fluid. The valve assembly may form part of an hydraulic servomotor system Figs. 2 and 3 (not shown). The pressure differential at the receiver ports is utilized to control the direction of movement of a spool valve the displacement of which from a neutral position determines the direction and speed of a fluid motor to which it is connected. A spring wire is connected between the spool valve and the jet pipe to provide a negative feedback loop so that when the spool valve has moved to a position proportional to the control signal applied to the transducers the forces acting on the jet pipe are balanced and the pipe returns to its central position and the movement of the spool valve ceases.

Title: Improvements in or relating to vacuum-controlled compressed-air valves for rail vehicle compressed air brakes
IPC: B60T15/18
Filed: 1966-09-08
Abstract: 1,121,766. Train braking system. KNORRBREMSE G.m.b.H. 8 Sept., 1966 [16 Nov., 1965], No. 40262/66. Heading F2F. In a vacuum controlled, air pressure operated braking system for rail vehicles, a control valve 5 is provided which is arranged to govern the compressed air loading of a brake cylinder and is controlled by a piston system providing piston surfaces arranged to be loaded by the pressure in the brake cylinder 26 and by the vacuum in the train pipe 1 against the vacuum in the vacuum reservoir 16 and a piston surface 12 arranged to be loaded by the vacuum in a control chamber 11 in the same direction as the loading of the piston surface by the train pipe vacuum, the control chamber being connected through an adjustable non-return valve 3 to the brake pipe, the brake pipe being connected by a return valve 6 to the control chamber and through a second adjustable non-return valve 3<SP>1</SP> to the vacuum reservoir 16. In the embodiment particularly described, the valve has three pistons 12, 14 and 19, but the pistons 12 and 19 may be combined to form a single piston. When the vacuum in train pipe 1 is decreased, valve part 18 moves upwards to close passage 17 and open valve 20, compressed air then flowing from reservoir 22 to chamber 24, to reset valve 20, and to the brake actuator cylinder 26. The adjustable valves 3, 3<SP>1</SP> permit the sensitivity and the maximum braking pressure of the system to be adjusted. To commence the braking operation the air flowing from pipe 1 into chamber 4, when the brake pipe vacuum is reduced, has to overcome the force applied by the degree of vacuum in chamber 11; this latter force may be varied by adjusting valve 3 to control the sensitivity of valve 5. The maximum braking pressure occurs when the pressure in the brake pipe is atmospheric. The pressure in cylinder 26 and in the valve re-setting chamber will then depend only on the degree of vacuum in reservoir 16 and compartment 2; this degree can be selected by adjusting valve 3<SP>1</SP> which controls flow from the reservoir to the evacuated train pipe.
