Abstract

443,797. Hydraulic apparatus. PEARSON, D. A., 21, Wake Green Road, Moseley, Birmingham. Oct. 20, 1934, No. 30072. [Class 69 (ii)] In order to exert a braking action when over-running is likely to occur, some of the operative liquid passes through a restriction to a small space between the inner and outer members of a hydraulic ram. The restriction may consist of a hole i, or of a clearance around the ring e and packing f. The invention may be applied to apparatus employing double or multiple lift rams.
