  • Patent number: 10421448
    Abstract: A retaining valve includes an inlet and a valve member downstream from the inlet, wherein the valve member has first, second, and third positions. A first passage through the valve member allows fluid flow through the retaining valve when the valve member is in the first position. A second passage through the valve member allows fluid flow through the retaining valve when the valve member is in the second position. A third passage through the valve member allows fluid flow through the retaining valve when the valve member is in the third position. A slide moves with respect to the valve member in response to pressure at the inlet. A spring engaged with the slide biases the slide toward the inlet. A seal located at an axial midpoint of the slide prevents flow through the third passage when pressure at the inlet is less than a predetermined pressure.

  • Patent number: 10415721
    Abstract: A micro electrical mechanical system (MEMS) valve is provided. The MEMS valve includes first and second bodies, a medium and a thermal element. The first body defines a first channel and a second channel intersecting the first channel. The second body defines a third channel and is movable within the first channel between first and second positions. When the second body is at the first positions, the second and third channels align and permit flow through the second and third channels. When the second body is at the second positions, the second and third channels misalign and inhibit flow through the second channel. The medium is charged into the first channel at opposite sides of the second body. The thermal element is proximate to the first channel and is operable to cause the medium to drive movements of the second body to the first or the second positions.
