Radial piston, hollow shaft motor - has grooves in radial pistons coupled by transverse bores to each radial piston bore

摘要

The hollow shaft, radial piston motor has a housing to enclose the shaft, fitted with a piston drum with radial piston cylinders. The axially bored pistons rest on a cam disc, fitted with pressure oil and oil return connections, using distributor pockets for loading the pistons with oil pressure and for oil return. A peripheral groove (14) in each piston (9) connects via a transverse bore (13) to the piston bore (12). The drum (7) has bores (26), which issue within the travel range of the piston groove and connect to the oil and return connections via the distributor (18) pockets (22, 23). USE/ADVANTAGE - For car track rod drive in reverse run, with compact design and very high output.
