Hydraulic-engine
The invention
  • The problem to be solved:
    The main aim was to create an engine that converts directly the hydrostatic energy of liquids into rotational motion mechanical power.
  • Definition:
    The object of the invention is a hydraulic-engine where the hydrostatic energy of the liquid introduced into its pressure area forces the rotary piston to develop a rotary movement and this way its axle delivers a useful mechanical power.
  • Presentation:
    The main parts of the invented engine construction are: the engine block with the sealing end-plates of the cylinder cavity and the bearing blocks, the rotary piston and the rotary control head. These parts are forming altogether the boundaries of the suction and the pressure cavities where the hydrostatic energy of the introduced liquid forces the rotary piston to develop a continuous and monodirectional rotary movement and this way its axle delivers a useful mechanical power. There is a one to one gear ratio forced coupling between the rotary piston and the rotary control head providing a proper coaction of these. Generally, two rotary pistons are built in into the hydraulic-engine with a 180 degrees of difference between their angular positions to eliminate the effect of the deadzone.

 

  • Application:
    In case of fluid medium it can primarily be used for the building of hydraulic-motors, stepless drives, break systems and high pressure pumps.
  • Advantages:
    The moving parts of the construction are exclusively rotary moving components and this way its operation is not influenced negatively by the acceleration forces that are common in case of alternate longitudinally moving parts. Consequently, such machines can be built that have excellent specific operational indices. Its other significant advantage is that simple to manufacture with a low cost because its components have plane surfaces and cylindrical forms.
  • Stage of development:
    A working model is available.
  • Documentation available: Yes
