NOT-FULLY-ROTARY HYDRAULIC ENGINE Russian patent published in 2009 - IPC F15B15/12 

FIELD: engines and pumps.

SUBSTANCE: proposed engine relates to machine building and can be used as a drive for whatever mechanisms. To relieve hydraulic engine shaft of external load, rotor shaft torque is transmitted to bearing unit outer ring via two-arm lever. Inner ring of aforesaid bearing unit represents hydraulic engine housing. Outer ring of aforesaid unit consists of two parts uniformly bolted together. Developed part of outer ring interacting with two-arm lever is linked up with the load. Hydraulic engine is damped, at end turning angles, with the help of throttling hole made in flexible plates fitted in engine housing grooves so that, when rotor comes against the stop, blade bore that discharges working fluid gets closed by aforesaid plate. Bearing unit design provides backlash-free operation and rules out jamming, since two parts of outer ring can move apart, while rotor damping reduces impact overloads.

EFFECT: higher efficiency.
