Abstract
A piston (1) for an actuator cylinder is formed of a radially inner metal core (17) and a radially outer surrounding casing body (23) moulded on the core, the latter having radially projecting anchoring structure (24) thereon embedded within the moulded body. The piston may be made bilaterally symmetrical with a plane of symmetry normal to the axis of reciprocation of the piston on a piston rod (8). Each of the two halves (15) of the piston adapted to be fitted on a piston rod is made up of a metallic core (17) with a radially projecting anchoring collar (24) thereon for making a strong join with an outer resin casing (23) molded onto the core. The anchoring part (24) has openings (25) to receive resin when the casing is produced. The casing makes direct running contact on the inner face of the cylinder. The piston (1) has plungers (37) at its two ends to run into holes in the end plates (4 and 5) of the cylinder to produce a dashpot braking effect. Such plungers are made integrally with the casing. A detector ring (32) is mounted in coaxial grooves (13) in the abutting faces of the two piston halves for detection of the position of the piston by an electromagnetic or the like system. <IMAGE>
