<p>The linear hydraulic motor has a differential piston working in a cylinder, and an assembly inside the piston and passing through the cylinder end wall. The piston is reciprocated by water pressure acting alternately against the piston front and rear faces under control of a valve, also discharging the water through the cylinder wall after pressure reduction. The larger diameter portion of the piston is in the front part of the motor. The two portions are accommodated in bores in the cylinder of different diameters, and there is a water inlet in the rear part of the larger bore, which has an end cover with a central drilling at the front, forming part of the valve discharging to the outside. The valve assembly incorporates an open cylinder, relieved so as to form collars at each end, acting as an auxiliary valve, with a ring forming a stop to restrict the forward movement.</p> |
