Hydraulic impulse rotational motor

A hydraulic impulse motor comprising:

• a turbine having a plurality of blades immersed in a hydraulic fluid;
• a fluid impulse source directed to one of said plurality of blades;
• and
• a pump connected to said turbine and said fluid impulse source, wherein said pump is driven by said turbine,
• whereby said fluid impulse source provides an impulse to the blades causing said turbine to rotate.

A hydraulic impulse motor comprising:

• a plurality of sections, each of said plurality of sections having a large and a small cylinder therein, said plurality of sections being serially connected such that each of the small cylinders opens to an adjacent large cylinder, said plurality of sections having a low pressure input end and a high pressure output end;
• a plurality of pistons, one of said plurality of pistons placed within each of said plurality of sections, each of said plurality of pistons having a large diameter portion matched to the large cylinder and a small diameter portion matched to said small cylinder;
• a valve connected to the low pressure input end;
• a controller connected to said valve;
• an impulse section having an impulse cylinder therein attached to the high pressure output end of said plurality of sections, said impulse section having an impulse output;
• a free piston placed within the impulse cylinder, said free piston positioned to contact one of said plurality of pistons, whereby high pressure energy is converted into kinetic energy;
• a turbine passage coupled to said impulse cylinder, said turbine passage being smaller than said impulse cylinder;
• a relief valve placed in said turbine passage;
• a turbine housing connected to the impulse output of said impulse section;
• a plurality of turbine blades rotating on a shaft within said turbine housing, the impulse output positioned to provide a fluid flow to one of said plurality of turbine blades, said turbine blades being substantially immersed in a hydraulic fluid;
• and
• a return passage connecting the hydraulic fluid within said turbine housing to the impulse cylinder,
• whereby the fluid flow created by said impulse section causes said plurality of turbine blades to move rotating the shaft for doing work.

A method of turning a shaft comprising the steps of:

• providing a low pressure source to a pressure amplifier;
• amplifying the low pressure from the low pressure source creating a higher pressure;
• using the high pressure to move a pressure piston;
• striking a free piston with said pressure piston, whereby energy from the high pressure is converted into kinetic energy in the free piston;
• generating an impulse of fluid from the kinetic energy of the free piston;
• and
• directing the impulse of fluid at a blade of a turbine causing the turbine to rotate.
