STATEMENT OR DISCLOSURE OF THE INVENTION :

The various embodiments of the piston devices disclosed in this invention are capable of exerting or delivering continuous net force or pressure upon one or more connected object(s) or device(s), for the purpose of generating motion in the object(s) or device(s) OR for the purpose of structure or frame or chassis based speed reduction and/or braking and/or safety, from the force of compressed and/or pressurized static (non-moving or non-flowing) working fluid(s) contained within the piston cylinder.

One important aspect of the various embodiments of this Invention is to ensure that the total net amount of thrust or force or pressure acting upon or in the direction of the piston-head or piston-heads is greater than the total net amount of reactionary thrust or pressure or force and its components acting in the opposite direction, while working with static working fluid(s). This invention provides a reduction mechanism to reduce or completely eliminate the opposing reactionary force (and its components) acting upon a piston or a series of pistons in the opposite direction, by diverting or channeling the reactionary pressure or force and its components in other directions in such a manner so that the piston is able to deliver a net amount of force or pressure, as is required or as is necessary, in the desired direction or directions of the piston-head or piston-heads, for the required duration, in various engineering systems and/or processes including but not limited to mechanically isolated engineering systems while working with compressed and/or pressurized static working fluid(s).

This is achieved by directing or channelling the required amount of force or pressure in the desired direction of the piston-head or piston- heads (as the case may be) and by reducing and/or completely eliminating the opposing pressure or force and its components, particularly reactionary force (and its components) acting in the opposite direction, by diverting or deflecting them in other directions and/or cancelling them within the apparatus or device itself, in such a manner so that the opposing forces and/or their components cancel each other out or otherwise gets significantly reduced within the device or apparatus itself and the piston device is able to deliver the required amount of net force or pressure in the required direction or directions of the piston-head or piston-heads (as the case may be) even when working with compressed and/or pressurized static working fluid or fluids.

This Invention utilizes one or more of several techniques to achieve its objectives, One technique is by placing angular or inclined or sloped or curved or other obstacles within the piston cylinder, particularly towards or at the back-end in a manner capable of deviating or diverting or deflecting or channelling the opposing forces and their components to reduce their effects significantly or remove their adverse effects completely, Another technique is by incorporating such mechanism in the design and/or shape of the piston cylinder, particularly in, towards or at the back-end portion of the piston devices to achieve similar result. This technique includes creation of piston device or devices with inclined or sloped or conical or angular or curved or other surfaces or bends to deviate and/or divert and/or channelize and/or re-direct and/or reduce the opposing pressure or thrust or force and its components, in or around or towards the back-end of the piston devices. The third technique is by placement of the piston device on an inclined stand or holder in such a manner that the direction or path of the backward pressure or thrust or force and its components is deliberately or purposefully kept or maintained in such a direction so that it does not adversely affect the efficient working of the piston device,

The angular, inclined, sloped, conical, curved or other objects and/or special design*s) and mechanism(s) incorporated, particularly in, at or towards the back-end of some of the embodiments of these special type of piston devices, and/or the inclined stand or holder effectively deflects and/or deviates and/or diverts and/or redirects and/or alters the path or direction and/or amount of the opposing pressure or thrust or force and its components, acting upon or towards the back-end of the piston device(s) particularly in the opposite direction, in such a manner that much of the pressure or force and its components acting in the backward or opposite direction gets diverted and/or cancels each other out completely or gets reduced significantly or drastically, thereby reducing and/or removing their adverse effects and ensuring the presence of net amount of required force in the desired direction or directions, acting upon or in the direction of the piston-head or piston-heads, for the required duration, from the force exerted by compressed and/or pressurized static (non-flowing and/or non- moving) fluid(s) contained within the piston-cylinder(s).
