HELICOID HYDRAULIC MOTOR Russian patent published in 2013 - IPC F03C2/08 F01C1/16 

FIELD: power engineering.

SUBSTANCE: hydraulic motor comprises a body with inlet and outlet nozzles, in the cavity of which there are two helical shafts. The master shaft is made with a larger diameter and represents an impeller, in which the end left and right grooves are made with a recess in the radial plane. The left groove is connected with the inlet nozzle, and the right one - with the outlet one. Nozzles are connected to each other with a pipeline, in the cross section of which there is a rotary stop valve with a rotation lever, equipped with a return spring and connecting by means of a traction rod with a handle on a control panel. The inlet nozzle is connected by means of two pipelines with a right injection nozzle and with a left discharge nozzle of a batcher. The outlet nozzle is connected by means of two pipelines with a right outlet and with a left injection nozzle of the batcher. In the batcher body there is a rotary shaft, on the lateral side of which there are three bores. The left and right bores are made with two radial conical bores and are permanently connected with a supply window of a supply nozzle of the batcher and with a drain window of a drain nozzle of the batcher, accordingly. Nozzles of the batcher are connected to each other with a pipeline, in the cross section of which there is a safety valve. The rotary shaft of the batcher is equipped with a rotary lever, which is fixed in working positions with ledges made on an adjustment rod.

EFFECT: development of stronger torque.
