Abstract

A joystick arrangement (10) for selectively actuating a group of valves is disclosed. The arrangement includes a base-plate (12) including four valve-actuating plungers (34) slidably disposed in the base-plate and positioned at the comers of a square with the handle (28), connected to the base-plate by a universal joint (30), at its centre. Four pins (36) project from the handle in a cruciform manner, the end of each of which engages with a slot (38) in the adjacent end of a respective plunger (34). This arrangement ensures that movements of the pin (36) parallel to the axis along which its respsective plunger (34) slides are transmitted to the plunger, but movements of the pin (36) of similar magnitude perpendicular to that axis are not. This in turn means that when any one of the plungers (34) is fully depressed, complete freedom of movement of the handle (28) about the other axis is retained to permit depression of either one of the two adjacent plungers (34) as required.
