FIELD: mechanical engineering; devices for opening and holding open rear doors, hood covers, and hatches of automobiles. SUBSTANCE: pneumatic resilient member has cylinder 1 hermetically closed from one end and filled with compressed gas and some liquid. Rod 2 arranged in cylinder has piston unit secured on its one end. Second end of rod projects from cylinder through sealing arrangement 3. Bushing 11 with axial step 12 is secured in zone of sealing arrangement in cylinder 1. Cup 10 is installed on rod 2 in zone of piston unit. Axial step 12 of bushing gets into cup space 13 when rod 2 is pulled out of cylinder. EFFECT: enhanced operation reliability, provision of soft limiting of opening stroke, increased manufacturability of parts of pneumatic resilient member. 3 cl, 3 dwg |
