Abstract
A stable flow regulator assembly includes a body having an aperture that received a tube. The assembly also includes a worm gear that extends through, and is rotationally movable relative to, the body. A worm wheel is rotationally positioned within the body and is pivotably moved within the body by engagement with the worm gear. The worm wheel also includes a slot, configured to align with the aperture, through which a tube may be extended, and as the worm wheel is moved within the body, the slot and the aperture are moved out of and into alignment to compress and release compression upon the tube.
Claims18
A stable flow regulator assembly for regulating fluid flow, comprising:
- a body comprising:
- a first side configured to be coupled to a second side;
- a first and second gear mount aligned on an axis between the first side and second side;
- a tube pathway configured to receive and retain a tube extending through the body;
- a worm gear comprising a gear thread and configured to be rotationally positioned through the first and second gear mount along the axis;
- and
- an actuator configured to be positioned within, and moveable relative to, the body, the actuator comprising teeth configured to engage the gear thread and a tube slot,
- wherein the body and the actuator are configured to receive the tube without extending an end of the tube through the tube pathway and the tube slot, and rotation of the worm gear translates to movement of the actuator within the body to move the actuator from an open configuration, wherein the regulator permits fluid flow, to a closed configuration, wherein the regulator restricts fluid flow.
A stable flow regulator assembly comprising:
- a body comprising:
- a first side configured to be coupled to a second side;
- the first and second sides each comprising respective first and second apertures, the apertures configured to be aligned when the first side is coupled to the second side;
- a first and second gear mount aligned on an axis;
- a worm gear comprising a gear thread and configured to be rotationally positioned through the first and second gear mount along the axis;
- and
- a worm wheel comprising a rotation axis, worm wheel teeth spaced from the rotation axis, and a tube slot, the worm wheel being configured to be rotationally held within the body, the worm wheel teeth being configured to engage the gear thread, and the tube slot being configured to align with the first and second apertures, wherein the body and the worm wheel are configured to receive a tube without extending an end of the tube through the first and second apertures and the tube slot,
- wherein rotation of the worm gear translates to rotation of the worm wheel and moves the tube slot relative to the first and second apertures.
A flow regulator assembly comprising:
- a body comprising an enclosed housing having an aperture extending through the body;
- a worm gear comprising a gear thread and configured to be rotationally positioned through the body;
- and
- a worm wheel configured to be rotationally positioned within the enclosed housing and to be moved rotationally by rotation of the worm gear, the worm wheel comprising a tube slot configured to align with the aperture,
- wherein the body and the worm wheel are configured to receive a tube without extending an end of the tube through the aperture and the tube slot, and rotation of the worm gear translates to rotation of the worm wheel within the body and moves the tube slot relative to the aperture.
