Abstract
The device comprises a housing (2,4), a piston, an electromagnetic coil (22), a valve control slide (82), a piston rod (28) and a return spring (116). The coil is energised to move the slide to align openings (100) with inlet or outlet valves. Hydraulic fluid is introduced via a port (P) to the inlet valve (88) and is discharged via the outlet valve (86) to a second port (T). Movement of the fluid in a chamber causes the piston to move. The piston rod then acts against the spring via the rod head. The piston may be double acting. The slide is sleeve shaped to receive the piston rod.
