Abstract

A power source comprises a reciprocating piston 2 which is drawn radially inwardly of a pressurised chamber 4 by suction between a cup 3 pivoted on the piston and a profiled cam wheel 1 on rotation of the cam wheel, and forced radially outwardly of the chamber by pressure within the chamber acting the cup when the profiled cam wheel releases from the suction cup. It is stated that the piston is drawn a distance into a pressurised chamber for less energy than the energy the piston can produce when forced a distance out of the chamber by the pressure. The power source may have many pistons connected via a crankshaft, say, and can be used as a motor vehicle power source, generator etc.

Description

<Desc/Clms Page number 1> PRESSURE POWER SOURCE This invention relates to the theory, principal, method and device which recovers a piston or mass a distance into a pressurised chamber for less energy than the energy the piston can produce when forced a distance out of the chamber by the chamber pressure. Power sources traditionally use fossil fuels e.g. internal combustion engine and are highly inefficient, expensive to run and cause major air pollution. Governments and industries are continually seeping to improve efficiency and reduce harmful emissions from power sources. According to the present invention there is provided a method for drawing a piston into a pressurised chamber comprising a piston, suction cup which is attached and can pivot on the piston, profiled cam wheel with shaft, the profiled cam wheel being adapted to allow the suction cup to slide on and off the wheel profile during wheel rotation, pressurised chamber which houses the suction cup, piston crown and profiled cam wheel. A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing:- Figure 1 shows the rotating profiled cam wheel contacting the suction cup attached to the piston which is forced out under chamber pressure and held in position by the piston stop. Figure 2 shows the profiled cam wheel rotated through 90 degrees (relative to figure 1). The profiled wheel has drawn the piston into the chamber by the attached suction cup. Figure 3 shows the profited cam wheel rotated through 180 degrees (relative to figure 1). The profiled wheel has now drawn the piston fully into the chamber. Figure 4 shows the profiled cam wheel rotated through 270 degrees (relative to figure 1) with the suction cup now uncovered. The suction cup and piston are now forced out to the piston stop by the internal chamber pressure. Figure 5 shows an end elevation of figure 1.

Referring to the drawing the device comprises a pressure chamber 4, profiled wheel 1 and shaft 6 which is off centre to produce an eccentric motion. A piston stop 5 and piston 2 with suction cup 3 attached and which can pivot about a fulcrum 7. In order to draw the piston 2 into the pressurised chamber 4 the profiled wheel 1 is rotated and makes contact with the suction cup 3 as shown in figure 1. Rotation and contact with wheel and cup has the effect of negating the internal pressure felt on top of the cup face whilst the pressure felt under the cup and on top of the piston 2 will balance. Further travel of the wheel will draw the piston into the chamber with the cup sliding over the wheel as shown in figure 2.

This motion continues until contact between wheel and cup is no longer made. The internal pressure will now be felt on top of the cup as shown in figure 3 and will force the piston out of the chamber until the piston reaches its stop 5 as shown in figure 4. Figures 1-4 shows one cycle of rotation.

Claims

CLAIMS 1. The theory/manner/process/technique/principal/system/way of/for using a pressurised chamber and device/method/mechanism to retrieving/draw-in a piston/mass and or attachment a distance into the chamber by reducing the force of the chamber pressure felt on the piston/mass and or attachment, and when the method of retrieval/drawing-in is ceased/released the chamber pressure will be felt on the piston/mass and or attachment, forcing the piston/mass and or attachment a distance out of the chamber.
2. A theory/manner/process/technique/principal/system/way as claimed in Claim 1, in the form of using a pressurised chamber and device/method/mechanism of retrieving/drawing-in a piston/mass a distance into the chamber, for less energy/force than the chamber pressure would exert on the piston/mass.
3. A device/method/mechanism comprising a pressure chamber, piston/mass, suction cup secured to and can pivot on the piston/mass crown, profiled cam wheel and shaft, the profile being adapted to allow the cam wheel to slide on, over and off the suction cup during its rotation and allowing the cup, when sliding on, and piston, to be drawn a distance into the chamber, and when off, forced a distance out of the chamber by the chamber pressure.
4. A system/device as claimed in Claim 2 or Claim 3, wherein the chamber pressure is higher than the pressure not enclosed by the chamber.
5. A system/device as claimed in any preceding claim, wherein the chamber encloses the piston/mass crown, suction cup and securing device, profiled cam wheel and shaft.
6. A system/device as claimed in any preceding claim, wherein the chamber encloses more than one piston/mass, suction cup with securing device, profiled cam wheel and shaft.
7. A system/device as claimed in any preceding claim, wherein a profiled cam wheel may service more than one piston-cup arrangement.
