Abstract (en)
[origin: US4519297A] To prevent distortion of the cylinder, and free running of the motion transfer element (6) thereon, in guide tracks (12) formed on the outside of the cylinder, the piston (5) is formed in two piston parts (22, 22') connected by a piston rod or pin (26, 26', 26a, 26a', 26b, 26b', 26c, 26c', 26d, 26d'), and the motion transfer element (6) is coupled to the piston rod or pin by a pair of fork-like portions (20) surrounding the pin and permitting limited radial movement. The pin or piston rod may be somewhat flexible, or made of flexible material, for example unitary with the piston parts (22, 22') and of plastic material, or may be made in two portions or parts (22, 22'; 22a, 22a' . . . ), each individually coupled to the fork-shaped element or merely retaining the fork-shaped element in position with end shoulders (25, 25') of the piston part axially engaging the fork-shaped element and hence transferring motion to the motion transmitting element (6).
