Abstract

It is common practise that pistons are machined or made from solid metal.
Novelty of invention is hollow piston that is filled with liquid. It is known fact that pressure is transferred differently in solids and liquids. This invention uses liquid to transfer pressure from one side of piston to another. Force is applaud on piston as it is common practise with hydraulic or pneumatic systems.
Invention can be used in any hydraulic or pneumatic system.

Description

Specification Drawing la) describes hydraulic or pneumatic system with hollow piston(20) that is filled with liquid inside closed space(100) Liquid piston(20) has opening(30) on one side so force can be applied directly on liquid. That way pressure that is generated from piston(25) at opening(30) is distributed by same amount at every point in liquid piston(20). As can be seen from drawing pressure inside piston will act in all direction and liquid piston(20) is not going to move in needed direction. To cancel force acting on area(40) fluid that is at front of liquid piston(20) needs to be moved at the beck of area(40). That way pressure on area(40) is cancelled and area(50) that receives pressure in needed direction is able to move liquid piston(20) in desired direction. Liquid piston(20) that is shaped in form of letter T is able to perform useful work.
Volume of fluid that is displaced with movement of liquid piston(20) is moving smaller piston(70) on other side of closed space( 100) There can be three different types of liquid piston as described in drawinglb) 1. Liquid piston that is made from cylinder that has opening on both sides. On one side of cylinder(80) is connected disc(40). To disc(40) is connected disc(SO) via small metal pins(55) That way there is no mantel(90) that connects discs(40) and (50).

2. Same liquid piston(20) only difference is physical connection between discs(40) and (50). Now solid mantel(90) is put to connect two discs(40) and (50) instead of pins(55) 3. Other type is liquid piston(20) with disc(60) that is shaped in form of sphere. That way volume of fluid that is displaced with liquid piston(20) will be larger.
There are two ways to transfer fluid inside closed space(100). One way is to drill small hole in discs(40) and (SO). That way when liquid piston(20) moves fluid inside closed space(100) will move from part A to part B through discs(40) and (50). That is only possible if liquid is used outside liquid piston(20).Other possibility is described in drawing la) where fluid in closed space( 100) is travelling via pipe( 110) that is put outside of space( 100).

Claims

1. Machine that works on principle of Pascal's law and hollow piston fild with fluid and has following characteristics:
a) hollow piston can be in any shape and size, b) it is capable to withstand high pressures c) there is opening on one side of hollow piston so force from outside acts directly on liquid in hollow piston.

2. Any machine or apparatus of claim 1, including compresors and pumps that uses hollow piston(s) filled with fluid together with application of Pascal's and Boyle's Law.

Claim in case of process;
1. Process of generating pressure inside container or piston filled with liquid and transfer that pressure to outside of container or piston 2. Process as defined in claim1 and pressurised fluid that will move solid piston in same system as piston filled with liquid.

3. Process defined in claim 2 were negative force or pressure generated by piston filled with liquid is cancelled and usfull work and energy is produced.

4. Any process where hollow piston(s) filled with fluid is used in application of Pascal's and Boyle's Law.
