Abstract
The present dashpot utilizes a spaced pair of post guides secured to opposed piston sidewall segments to connect the piston to the inner sidewall surface of the cylinder. The guide pair essentially precludes motion of the piston within the cylinder along the first axis connecting the guides while limiting motion of the piston within the cylinder along a second axis transverse to the first axis and the cylinder axis in response to limited misalignment of the axis of the cylinder and the axis of the piston rod.
