Abstract
A fluid transfer apparatus utilizing a slanted cain disk to oscillate and rotate a set of pistons arranged in a circle. Channels associated with the pistons and piston housing effect the transfer of fluid from a first location to a second location, as well as the pressurization or depressurization of the fluid, during movement of the pistons. The apparatus can be used as a high-pressure fluid pump, a fluid-powered motor, a fluid distribution valve, or another fluid transfer device.
Claims25
A fluid transfer apparatus, comprising:
- a torque transmitter;
- a rotary device associated with the torque transmitter;
- three or more pistons arranged substantially in a circle;
- a piston housing permitting axial and rotational movement of the pistons;
- an oscillator associated with the rotary device causing axial oscillation and rotation of the pistons during rotation of the rotary device;
- and
- channels associated with the pistons and piston housing for effecting the transfer of fluid from a first location to a second location as the pistons oscillate.
A pump for pressurizing and transferring fluid, comprising:
- a rotatable cam having a first side, and a slanted second side;
- a motor-driven shaft in communication with the first side of the cam;
- a piston housing including three or more piston cavities arranged substantially in a circle;
- three or more pistons capable of axial rotational movement, each having a first end in communication with the slanted second side of the rotatable cam, and a second end in a piston cavity;
- and
- inlet and outlet channels in the piston housing and pistons for effecting the transfer and pressurization of fluid during movement of the pistons.
A fluid-powered motor, comprising:
- a rotatable cam having a first side, and a slanted second side;
- a drive shaft in communication with the first side of the cam;
- a piston housing including three or more piston cavities arranged substantially in a circle;
- three or more pistons capable of axial and rotational movement, each having a first end in communication with the slanted second side of the rotatable cam, and a second end in a piston cavity;
- and
- inlet and outlet channels in the piston housing ad pistons for effecting the transfer of pressurized fluid to sequentially oscillate the pistons, causing rotation of the cam and drive shaft.
A fluid distribution valve, comprising:
- a rotatable cam having a first side, and a slanted second side;
- a piston housing including three or more piston cavities arranged substantially in a circle;
- three or more pistons capable of axial and rotational movement, each having a first end in communication with the slanted second side of the rotatable cam, and a second end in a piston cavity;
- inlet channels in the piston housing;
- inlet channels in the pistons communicating with the inlet channels in the piston housing during movement of the piston, and with the piston cavities;
- distribution channels in the piston cavities communicating with the exterior of the piston housing;
- outlet channels in the piston housing;
- and
- outlet channels in the pistons communicating with the piston cavities, and with the outlet channels in the piston housing.
