    DESCRIPTION

    Alternative discontinuous to continuous rotary movement converter.

    Technical Field of the Invention 5

    The present invention belongs to the technical field of the conversion of thermal energy to mechanical and / or electrical energy by means of an alternative thermal machine (MA) or an internal combustion engine (MCI), which transmit the alternative movement to continuous rotary movement. 10

    Object of the invention

    The objective of the present invention called "DISCONTINUOUS ALTERNATIVE MOVEMENT CONVERSOR TO CONTINUOUS ROTARY", is the efficient conversion of thermal energy to mechanical and / or electrical energy by means of conventional alternative cylinders that operate with a thermal cycle that includes processes closed to volume constant during which the piston remains at rest, while the power supply shaft rotates at continuous speed.
     twenty
    Background of the invention

    The conversion plants of thermal energy to mechanical energy and / or electrical energy that operate with alternative machines or alternative internal combustion engines convert the alternative movement to rotary movement by means of connecting rod-crankshaft. 25

    Alternative machines whose thermal cycle contains processes during which the volume of the cylinder remains constant (plunger and shank at rest) give rise to discontinuous crankshaft movement, and for that reason they are useless.
     30
    The invention referred to as DISCONTINUOUS ALTERNATIVE MOVEMENT CONVERSOR TO CONTINUOUS ROTARY is different from the aforementioned mechanisms that convert the alternative movement to rotary movement by means of a crankshaft connecting rod in which the DISCONTINUOUS ALTERNATIVE MOVEMENT CONVERSOR TO CONTINUOUS ROTARY movement can transfer the discontinuous movement of a cylinder from a discontinuous movement 35 actuator to a rotating shaft by means of two intermediate hydraulic cylinders connected by their pistons and rods, where the first of which is capable of blocking the movement of the piston of the actuator cylinder to keep the volume of the cylinder constant at each end of its stroke , while the second one unlocks the connection between the piston of this hydraulic cylinder and the rotary axis so that this axis can move freely when the piston of the actuator cylinder remains at rest, or by means of the hydraulic cylinder blocking the piston movement of the actuator cylinder for maintenance er the volume of the constant cylinder at each end of its stroke, while to lock and unlock the connection between the piston of the hydraulic cylinder and the rotary axis, a mechanical connection device is used for alternating rectilinear motion discontinuous to continuous rotational movement. Based on the principle of operation of the invention, there are no known movement conversion technologies from discontinuous alternative to continuous rotary of this nature.

    Brief Description of the Invention 50

    The invention called DISCONTINUOUS DISCONTINUOUS ALTERNATIVE MOVEMENT CONVERSOR TO CONTINUOUS ROTARY, with two implementations a and b, consists of the implementation a), in a mechanism formed by two hydraulic cylinders and a
    converter from translation to rotation movement based on a toothed rack with reciprocating linear motion that meshes with a partially cogged wheel in axial direction with continuous rotation movement; and in the implementation b), in the first hydraulic cylinder capable of blocking the movement the piston of the actuator cylinder to keep the volume of the cylinder constant at each end of its stroke while to lock and unlock the connection between the piston of the hydraulic cylinder and the rotary axis is used a mechanical device connecting between the rod and the connecting rod to transform the discontinuous alternative rectilinear movement to continuous rotation movement.
     10
    The alternative machines whose thermal cycles that involve processes during which the volume of the cylinder remains constant (piston and shank at rest), are subject to an alternative discontinuous movement, which is not useful for directly coupling a crankshaft by means of the conventional connecting rod. For this reason, the rod of the actuator cylinder is coupled to a rotational movement to rotational movement converter 15 by means of two intermediate hydraulic cylinders in the implementation a), or a mechanical connection system in the implementation b). The invention called CONTINUOUS ROTARY ALTERNATIVE MOVEMENT CONVERSOR transfers the discontinuous and alternative movement of the piston and its rod from a double-acting actuator cylinder to a rotary axis by means of the converter of alternating discontinuous translation movement to continuous rotation movement, which is carried out in the implementation a) by means of two intermediate hydraulic cylinders connected by their pistons and rods, where the first of which is responsible for blocking the movement of the piston of the actuator cylinder to keep the volume of the cylinder constant in each end of its stroke, while the second 25 disconnects the connection between the piston of this hydraulic cylinder and the rotary axis so that this axis can move freely when the piston of the actuator cylinder remains at rest, while in implementation b) the coupling and decoupling between the cylinder rod acting or and the connecting rod is made by a mechanical system. 30
