Abstract
A pressurized fluid supply apparatus and method of supplying pressurized fluid is provided. The pressurized fluid supply apparatus includes a housing configured to rotate about an axis, at least one fluid pump coupled to the housing and configured to pressurize a fluid therein, and at least one movable element disposed within the housing. The at least one movable element is configured to move within the housing when the housing rotates about the axis, which causes the at least one movable element to be in periodic driving engagement with the at least one fluid pump to cause the fluid to be pressurized.
Claims19
A pressurized fluid supply apparatus, comprising:
- a housing configured to couple to a component and to rotate about an axis responsive to rotation of the component;
- a first fluid pump coupled to the housing, wherein the first fluid pump is activated when the component rotates and wherein activation of the first fluid pump pressurizes a fluid;
- and
- at least one movable element enclosed within a channel of the housing and configured to move therein when the housing rotates about the axis, wherein the channel circumferentially extends around the axis;
- wherein the at least one movable element is in periodic driving engagement with the first fluid pump to cause the fluid to be pressurized to a first pressure;
- and
- wherein the first fluid pump includes a reciprocating piston reciprocating in an axial direction relative to the housing and at least one cam follower and wherein the at least one cam follower is hemispherically-shaped and is positioned within a wall of the channel.
A pressurized fluid supply apparatus, comprising:
- a housing configured to rotate about an axis;
- at least one fluid pump coupled to the housing, wherein the at least one fluid pump configured to pressurize a fluid, wherein the at least one fluid pump is activated when the component rotates, and wherein activation of the at least one fluid pump pressurizes a fluid;
- and
- at least one movable element enclosed within a channel of the housing and configured to move therein when the housing rotates about the axis, wherein a movement of the at least one movable element within the housing is substantially independent from a rotation of the portion of the at least one fluid pump about the axis, and wherein the at least one movable element is in periodic driving engagement with the portion of the at least one fluid pump to cause the fluid to be pressurized;
- wherein the channel circumferentially extends around the axis;
- and
- wherein the first fluid pump includes a reciprocating piston reciprocating in an axial direction relative to the housing and at least one cam follower and wherein the at least one cam follower is hemispherically-shaped and is positioned within a wall of the channel.
A method of supplying pressurized fluid, the method comprising:
- activating at least one fluid pump in a pressurized fluid supply apparatus by rotating a component coupled to a housing of the pressurized fluid supply apparatus;
- while the at least one fluid pump is activated, causing at least one movable element in the pressurized fluid supply apparatus to periodically drivingly engage a camming element in the at least one fluid pump to cause a fluid to be pressurized;
- wherein the at least one movable element is enclosed within a channel of the housing and configured to move therein when the housing rotates;
- wherein the channel circumferentially extends around an axis of rotation of the housing;
- and
- wherein the first fluid pump includes a reciprocating piston reciprocating in an axial direction relative to the housing and at least one cam follower and wherein the at least one cam follower is hemispherically-shaped and is positioned within a wall of the channel.
