Abstract
A fluid pressurization apparatus utilizing a slanted cam disk to oscillate, or to oscillate and rotate a set of piston assemblies arranged in a circle. The motion of the pistons is utilized to pressurize fluid or to perform work. The piston assemblies have multiple elements configured to allow the plungers to be engaged or disengaged to the motion of a disk by manipulating a working fluid introduced into the apparatus. By virtue of these disengageable plungers, the apparatus can be disabled and resumed at will. This apparatus is particularly well suited for pressurizing liquids such as water for high-pressure and high-flow applications.
Claims27
An apparatus for transferring and applying pressure to fluids, comprising:
- a housing having an internal housing cavity containing a working fluid;
- a drive shaft communicating with the internal housing cavity;
- a first rotatable cam disk having a first end communicating with the drive shaft and a second end, the second end having a surface which is slanted relative to a plane perpendicular to the drive shaft;
- a plurality of pistons in the housing cavity, each piston having a first end communicating with the slanted surface of the first cam disk and a second end away from the first cam disk;
- a plurality of piston chambers in the internal housing cavity, each piston chamber housing a piston and having first and second piston cavities, the first end of the piston being in the first piston cavity and the second end of the piston being in the second piston cavity, the second piston cavity containing a system fluid;
- one or more piston seals positioned on each piston separating the working fluid from the system fluid;
- one or more fluid supply channels communicating with the piston chambers;
- and
- one or more fluid outlet channels communicating with the piston chambers;
- wherein axial movement of the pistons effected by rotation of the cam disk pressurizes system fluid in the second piston cavities of the piston chamber, and forces the system fluid into the one or more fluid outlet channels.
A fluid-powered intensifier, comprising:
- a housing having an internal housing cavity containing a working fluid;
- a drive shaft having one end in the housing cavity;
- a first rotatable cam disk having a first end communicating with the drive shaft and a second end, the second end having a slanted surface;
- a plurality of pistons in the housing cavity, each piston having a first end communicating with the slanted surface of the first cam disk and a second end away from the first cam disk;
- a plurality of piston chambers having walls surrounding the pistons, the plurality of piston chambers containing system fluid;
- one or more piston seals positioned on each piston separating the working fluid from the system fluid;
- grooves within the pistons defining piston fluid passages between the pistons and piston chamber walls;
- and
- first inlet and first outlet fluid passages in the intensifier communicating with the grooves in the pistons.
A direct-drive pump, comprising:
- a housing having an internal housing cavity containing a working fluid;
- a drive shaft having a first end in the housing cavity and a second end;
- a power source for applying torque to the drive shaft;
- a first rotatable cam disk having a first end communicating with the first end of the drive shaft and a second end having a slanted surface;
- a plurality of pistons in the housing cavity, each having a flat end communicating with the slanted surface of the first cam disk and a second end away from the first cam disk;
- a plurality of piston chambers containing a system fluid separate from the working fluid and having walls surrounding the pistons;
- grooves within the pistons defining piston fluid passages between the pistons and piston chamber walls;
- and
- first inlet and first outlet fluid passages in the intensifier communicating with the grooves in the pistons.
