Title: Improvements in or relating to fluid pressure control valves
IPC: B60T15/04
Filed: 1950-05-22
Abstract: 678,474. Fluid-actuated valves. BENDIX AVIATION CORPORATION. May 22, 1950 [May 21, 1949], No. 12798/50. Class 135 [Also in Group XXXIV] A self-lapping valve 24, Fig. 1, for operating the trailer brakes 16 of a tractortrailer vehicle 10, 12, comprises a three-part casing 32, Fig. 2 (brakes released position), having chambers 46, 42, 44 connected respectively to the atmosphere, a brake control line 26 communicating with a power device 18 operating the trailer brakes 16, and a line 23 communicating with a vacuum tank 22. The chambers 42, 44 are separated by a flexible diaphragm 48 sealingly mounting a tubular member 88 urged upwardly by a spring 84, whilst the chambers 42, 46 are separated by a casing wall 72 through which slidingly passes a tubular member 52 urged downwardly by a spring 78. The diaphragm is reinforced by flanged ring members 92, 90, which engage a casing boss 98 and a fixed partition 100 respectively to restrict the movement of the diaphragm. The tubular member 52 is belled out at its lower end to mount a rubber valve disc 58 urged downwardly by a spring 60 to engage a seat member 56 and the upper end of the member 88, and slotted at its upper end to mount a transverse rod 68 engageable by a helical cam surface 76 formed on the tubular end 74 of a rotatable operating member 30. To apply the brakes 16, the member 30 is rotated clockwise viewed from above, whence the cam surface 76 is lowered, the tubular member 52 and the valve disc 58 being urged downwardly by the springs 78, 60 until the valve disc engages the tubular member 88. In this position, the brake line 26 is isolated from both the atmosphere and the vacuum tank. On further clockwise movement of the member 30, the seat member 56 is moved away from the disc 58 to admit air to the chamber 42 to urge the diaphragm 48 downwards, the disc 58 being held in engagement with the tube 88 by the spring 60. At this stage, the brakes are partially operated, the disc 58 following up the movement of its seat 56 to float between the open and closed positions. To apply full braking effort, the clockwise rotation of the member 30 is continued until the downward movement of the diaphragm is arrested by the engagement of the flanged ring 92 with the boss 98 and further downward movement of the disc 58 is prevented so that it no longer follows up the movement of its seat 56, the brake line 26 is then continuously open to atmosphere through the chamber 42. To dampen any vibration tendencies of the diaphragm 48 when the brakes are partially applied, i.e. during the follow-up stage of the disc and its seat, restricted passages are provided on either side of the diaphragm between the tubular member 88, the boss 98 and the partition 100.

Title: Generating systems including alternators
IPC: H02J7/14
Filed: 1970-03-17
Abstract: 1310937 Vehicle generating systems for charging batteries AUTOMOBILES CITROEN SA 17 March 1970 [20 March 1969] 12897/70 Heading H2H A generating system comprising an alternator driven at varying speeds has the alternator windings in a plurality of parts which parts are connected in different functional manners according to whether or not the speed at which the alternator is being driven is above or below a predetermined value. A generating system is provided with an alternator 1 the winding of which is in two parts 2, 3. The alternator is connected so as to charge a battery E by way of a full wave rectifier 4 and the coil 11 of a current relay. The rectifier 4 includes a pair of semi-conductor diodes 5, 6 and a pair of thyristors 7, 8 the trigger electrodes e of which are connected to the battery negative terminal by way of resistors 14, diodes 13 and the normally closed contact 12 of the current relay. A diode 15 is connected between the negative terminal G of the rectifier 4 and the junction P of the alternator winding parts 2, 3. Whilst the alternator speed is below a predetermined value the current generated thereby is insufficient to operate the current relay 11 and the contact 12 remains closed. Firing pulses are then applied to the thyristors 7, 8 so that the winding parts 2, 3 are used simultaneously with the output thereof rectified by the bridge 5-8. As the alternator speed increases the current output increases until at the predetermined speed the relay 11 operates to open contact 12. The firing pulses for the thyristors then disappear with the effect that the winding parts 2, 3 now function singly and alternately, the output of the part 2 being rectified by diodes 5, 15 and that of the part 3 by diodes 6, 15. In another single phase embodiment the rectifying bridge 4 comprises four diodes and is connected in series with a thyristor receiving firing pulses by way of the contact 12. A system having a three phase alternator and rectifier bridge is also described.
