Abstract

The present invention includes a liquid filling, pressurization and release apparatus and method for filling, pressurizing and releasing liquids into a system. One embodiment of the present invention includes a liquid pressurization and release apparatus including a housing, a discharge aperture positioned on one end of the housing, a slidable disk disposed within the housing to form a chamber suitable to fill, pressurize and release a liquid, a compression mechanism attached to the slidable disk and a tensioning mechanism coupled to the slidable disk to pressurize and maintain pressure in the chamber.

1 . A liquid pressurization and release apparatus comprising: 
 a housing;    a discharge aperture positioned on one end of the housing;    a slidable disk disposed within the housing to form a chamber suitable to fill, pressurize and release a liquid;    a compression mechanism attached to the slidable disk; and    a tensioning mechanism coupled to the slidable disk to pressurize and maintain pressure in the chamber.    
   
   
       2 . The apparatus of  claim 1 , wherein the tensioning mechanism comprises one or more springs.  
   
   
       3 . The apparatus of  claim 1 , wherein the tensioning mechanism comprises a spring rated between about 400 1600 pounds.  
   
   
       4 . The apparatus of  claim 1 , wherein the tensioning mechanism comprises a pneumatic mechanism, a hydraulic mechanism, a electric mechanism, a magnetic mechanism, a mechanical mechanism or a combination thereof.  
   
   
       5 . The apparatus of  claim 1 , wherein the compression mechanism comprises a rod attached to the compression disk that slidably penetrates the housing, whereby the movement of the rod compresses the tension mechanism.  
   
   
       6 . The apparatus of  claim 1 , further comprising a threaded screw aperture in the housing, wherein the compression mechanism selectively engages and disengages with the threaded screw aperture, whereby the compression mechanism is engaged to compresses the tension mechanism.  
   
   
       7 . The apparatus of  claim 1 , wherein the compression mechanism comprises a gear box attached to the housing and a threaded rod attached to the compression disk that slidably penetrates the housing, wherein the gear box selectively engages and disengages with the threaded rod, whereby the tension mechanism is compressed when the compression mechanism is engaged.  
   
   
       8 . The apparatus of  claim 1 , wherein the compression mechanism is engaged manually, pneumatically, hydraulically, mechanically or a combination thereof.  
   
   
       9 . The apparatus of  claim 1 , wherein the slidable disk comprises one or more sealing rings positioned between the slidable disk and the housing.  
   
   
       10 . The apparatus of  claim 1 , wherein the slidable disk is connected to an expandable bladder positioned between the slidable disk and the end of the housing, to form the chamber.  
   
   
       11 . The apparatus of  claim 1 , wherein the discharge aperture comprises a valve that includes settings to selectively control the pressure of the liquid as it is released.  
   
   
       12 . The apparatus of  claim 1 , wherein the apparatus generates a generally constant pressure at the discharge aperture.  
   
   
       13 . The apparatus of  claim 1 , wherein the pressure at the aperture is between about 5 and 100 psi.  
   
   
       14 . The apparatus of  claim 1 , wherein the discharge aperture is adapted to attach to a fuel system.  
   
   
       15 . The apparatus of  claim 1 , wherein the apparatus further comprises a handle, one or more legs, a attachment mechanism or a combination thereof.  
   
   
       16 . An apparatus for pressurization and release of a liquid comprising: 
 a housing having a first end and a second end, wherein the first end has a notched aperture and the second end has a discharge aperture;    a slidable disk disposed within the housing to form a fluid displacement chamber;    a spring disposed in the housing between the slidable disk and the first end of the housing, such that compressing the spring draws into the fluid displacement chamber and decompressing the spring pressurizes the liquid in the fluid displacement chamber; and    a rod attached to the slidable disk and engaging the notched aperture, to compress the spring and decompress the spring.    
   
   
       17 . A method of pressurizing and releasing a liquid into a system comprising the steps of: 
 providing a pressurization and release apparatus comprising a housing having an aperture, a slidable disk disposed within the housing to form a chamber suitable to fill, pressurize and release a liquid, a compression mechanism attached to the slidable disk, and a tensioning mechanism coupled to the slidable disk;    attaching the aperture of the pressurization and release apparatus to a system; and    releasing the pressurized liquid into the system.    
   
   
       18 . The method of claim  26 , further comprising the steps of filling and pressurizing the a pressurization and release apparatus, wherein the step of filling and pressurizing the a pressurization and release apparatus includes attaching the aperture of the pressurization and release apparatus to a system and activating the compression mechanism, whereby the compression mechanism compresses the tensioning mechanism and the liquid fills the apparatus and compression mechanism is released so that the tension from the tension mechanism pressurizes the apparatus.  
   
   
       19 . The method of claim  26 , wherein step of releasing the pressurized liquid into the system produces a generally constant pressure at the aperture.  
   
   
       20 . The method of claim  26 , wherein the step of filling a pressurization and release apparatus comprises attaching the aperture of the pressurization and release apparatus to a connection hose.
