Abstract

An actuation system particularly for a vehicle clutch, in which a source of pressurised fluid is interconnected with a slave cylinder (11) via a displacement means (12). The displacement means (12) includes a component which is displaced by the pressurised fluid from the source to provide a displacement proportional to the actuating movement of the slave cylinder (11) caused by the pressurised fluid, and a sensing means is provided which is operable to measure the displacement to indicate the actuating movement of the slave. Various displacement means in the form of valves are disclosed together with a mechanism for interconnecting the operation of a vehicle clutch and throttle. <IMAGE>
