Abstract (en)
[origin: EP0161919A2] A fluid pressure actuator has a cylinder (2) comprising a rectilinearly displaceable piston (10) that acts on a drive member (40) to rotate the drive member during a first, greater part of the stroke of the piston and then moves the drive member rectilinearly for the remaining part of the stroke. The rotation is generated by a spiral cam mechanism (26, 42). Further cam means (48, 52, 48) restrain linear displacement of the drive member during the first part of the stroke but permit its rotation to a predetermined angular position and thereafter said further cam means restrain said rotation but permit said linear displacement by the piston. Cushioning means (70, 84) are provided whereby the end of the rotational movement preceding the linear movement are cushioned, but not the linear movement.
