Title: Improvements in or relating to servo clutch operating systems for motor vehicles
IPC: B60K23/02
Filed: 1932-06-28
Abstract: 399,620. Operating clutches. CLAYTON DEWANDRE CO., Ltd., Titanic Works, and FAGARD, J., 24, Eastgate, both in Lincoln. June 28, 1932, No. 18258. [Class 80 (ii).] A control valve for an enginesuction servomotor operating the clutch of a motor-vehicle comprises a valve casing 4, Fig. 2, divided into two chambers 5, 6 communicating respectively with the working chamber of the servo and with the engine intake, and a valve stem 9 mounted to slide in the casing, through which it projects at both ends. The stem is tubular, with a partition 12, and the lower end is closed by a plug 13, the stem being urged downwards by a spring 15. Ports 16, 17, 18 and 19, 20 are formed in the stem respectively below and above the partition, the arrangement being such that when the stem is in its upper position, as shown, the chamber 5 is in communication with the chamber 6 and is isolated from the atmosphere and the servo thus operates to disengage the clutch, while as the stem is moved downwards communication between the two chambers is gradually throttled and the chamber 5 is simultaneously gradually brought into communication with the atmosphere, thus causing clutch engagement. The stem 9 is controlled by a bell-crank lever, one arm 21 of which bears against the plug 13 while the other arm 22 is connected by a link 24 to a manual control element, preferably the accelerator, the rate of clutch engagement thus being dependent on the rate of depression of the accelerator. The fulcrum 23 of the lever is mounted on a disc 26 having an arm 28 connected by linkage 29 to an adjusting lever so that, by operation of the latter, the disc 26 can be turned about its axis so as to adjust the position of the stem relative to the accelerator. By moving the adjusting lever to one extreme position, the servo mechanism is rendered inoperative. Air pressure may be employed instead of engine suction. In a modification, a spring-loaded ball valve 31, Fig. 3, with a restricted byepass 34, is mounted on the upper end of the stem 9. When, during the downward movement of the stem, ports 36 enter the chamber 5 and the pressure in the stem above the partition consequently falls, the valve 31 opens so as to admit air rapidly to the chamber 5, resulting in a rapid movement of the clutch to partiallyengaged position. But as soon as the pressure in chamber 5 rises to a predetermined value, the valve 31 again closes, restricting the further admission of air, whereby the clutch moves into full engagement at a slower rate.
