| description | For retarding the motion of a piston traveling on its forward stroke in an air cylinder, a hydraulic cylinder having shorter piston stroke than that of the air cylinder is mounted on its rear side in axial alignment therewith. The piston rod of the hydraulic cylinder projects into the air cylinder to be telescopically received in an axial bore formed through the rear end portion of the air cylinder piston rod. Hence, as the air cylinder piston travels forwardly in the usual manner to a predetermined point intermediate both extremities of its stroke, a larger diameter portion on the front end of the hydraulic cylinder piston rod engages the air cylinder piston at the rear end of the aforesaid axial bore. The forward motion of the air cylinder piston is thereafter retarded by the hydraulic cylinder piston also traveling forwardly against the resistance offered by hydraulic fluid in the intercommunicated chambers of the hydraulic cylinder. The passageway intercommunicating the hydraulic fluid chambers can be closed by a solenoid-operated shut-off valve whereby the air cylinder piston traveling forwardly at reduced speed as above can be stopped whenever required. |
