A metal frame is disposed between the first and the second faces, the metal frame supporting a first feature extending outwardly from opposing planar sides of the frame towards the first and the second faces, as well as supporting a second feature also extending outwardly from opposing planar sides of the frame towards the first and the second faces. The first feature is compressible when pressure is applied to the first and the second faces, and the second feature is incompressible when the pressure is applied to the first and the second faces. The first and the second features are continuous and concentrically aligned with one another about the through-hole, and the first feature is inclined towards the through-hole. | 2022-07-21 |
20220228664 | Electronic Expansion Valve - Some embodiments of the present invention provides an electronic expansion valve, including: a valve body, the valve body having a valve port; a valve head, movably provided in the valve body, the valve head being configured for blocking the valve port; a rod member, the rod member having a first end and a second end opposite to each other, wherein the first end is provided in a cavity of the valve head in a penetrating manner, the second end has a positioning structure, the positioning structure is configured for positioning a circumference of the rod member, the positioning structure is a positioning flat surface, and the positioning flat surface is parallel to an axis of the rod member; a valve sleeve, provided in the cavity of the valve head. | 2022-07-21 |
20220228665 | FLUID CONTROL VALVE, FLUID CONTROL DEVICE, VALVE ELEMENT, AND METHOD OF MANUFACTURING VALVE ELEMENT - To avoid formation of surface sag formed when an internal flow path of a valve element is processed and to ensure a maximum flow rate in a fluid control valve where a seating surface of the valve element is formed of a resin layer, in a fluid control valve that includes a valve seat, and a valve element including resin layers provided in concave grooves formed on a facing surface facing the valve seat, the valve element further includes internal flow paths whose inflow ports are opened in a back surface facing away from the facing surface and whose outflow ports are opened in portions around the concave grooves on the facing surface, and counterbored portions are formed on sides of the inflow ports of the internal flow paths. | 2022-07-21 |
