Abstract
A flow control device includes a housing forming an inlet passage, an outlet passage, and a fluid passageway between the inlet passage and the outlet passage. A magnetized shaft is positioned entirely within the housing between the inlet passage and the outlet passage and a plurality of vanes are secured to the magnetized shaft and positioned in the fluid passageway. A first wire coil is moveably positioned around a first end of the magnetized shaft, external of the housing, and is linearly moveable in a direction parallel to a longitudinal axis of the magnetized shaft.

A flow control device, comprising:
- a housing forming an inlet passage, an outlet passage, and a fluid passageway between the inlet passage and the outlet passage;
- a magnetized shaft positioned entirely within the housing between the inlet passage and the outlet passage;
- a plurality of vanes secured to the magnetized shaft and positioned in the fluid passageway;
- and
- a first wire coil moveably positioned around a first end of the magnetized shaft, the first wire coil being external of the housing and linearly moveable in a direction parallel to a longitudinal axis of the magnetized shaft.
A flow control device, comprising:
- a housing forming an inlet passage, an outlet passage, and a fluid passageway between the inlet passage and the outlet passage;
- a shaft positioned entirely within the housing between the inlet passage and the outlet passage;
- a first magnet secured to the shaft proximate a first end of the shaft;
- a plurality of vanes secured to the shaft and positioned in the fluid passageway;
- and
- a first wire coil moveably positioned around the first end of the shaft, the first wire coil being external of the housing and linearly moveable in a direction parallel to a longitudinal axis of the shaft.
A method of pressure control in a fluid flow, comprising:
- positioning a shaft entirely within a housing, the housing forming an inlet passage, an outlet passage, and a fluid passageway between the inlet passage and the outlet passage;
- securing a plurality of vanes to the shaft and positioning the plurality of vanes in the fluid passageway;
- positioning a first wire coil around a first end of the shaft, the first wire coil being external of the housing and linearly moveable in a direction parallel to a longitudinal axis of the shaft;
- positioning the housing in a path of the fluid flow;
- and
- moving the first wire coil relative to the first end of the shaft to control the pressure in the fluid flow.
