A fluid pulse dampener with automatic pressure-compensation is provided. A system of chambers and channels in the dampener creates an internal feedback mechanism that increases or decreases a compensating pressure on the membrane in response to increases or decreases in the pressure of a fluid moving past the other side of the membrane. Variations of the pulse dampener allow for the input and/or output of gas flow is be restricted or increased as may be desired.

Pulse dampener with automatic pressure-compensation

A device which includes a pulse dampener and a degasser or de-bubbler. The device includes a fluid flow path and a fluid chamber located within the device. In addition, the device includes a pulse dampening membrane for dampening pulses in the fluid as it flows through the device. The device also includes a degassing membrane for degassing the fluid as it flows through the device, and/or a de-bubbling membrane for removing gas bubbles from the fluid as it flows through the device. The degassing or de-bubbling membrane can be separate and distinct from the dampening membrane. The de-bubbling membrane can be in addition to or in place of the degassing membrane in some embodiments.

Degassing, de-bubbling, and dampening device

A rotary shear valve having a rotor device and a stator device both with planar faces. The stator face includes a central port located at a common rotational axis, a second port radially spaced a radius Rfrom the central port, and a third port spaced at radius R. The second and third ports are in general linear alignment with the central port. The rotor face includes a first rotor groove extending radially outward from the common rotational axis to a position at radius Rfrom the central port. The rotor device is rotatably mounted to the stator device for rotation thereof about the axis, providing fluid-tight, selective relative rotation therebetween between two or more discrete rotor positions. When in a discrete first rotor position, the first rotor groove is oriented in radial alignment with, and fluidly connects, the central port and the second port with the third port.

Multi-position, micro-fluidic valve assembly with multiple radial grooves to enable individual or combined flows

A fluid pulse dampener with automatic pressure-compensation is provided. A system of chambers and channels in the dampener creates an internal feedback mechanism that increases or decreases a compensating pressure on the membrane in response to increases or decreases in the pressure of a fluid moving past the other side of the membrane. Variations of the pulse dampener allow for the input and/or output of gas flow to be restricted or increased as may be desired.
