摘要： A high conductance valve for use in fluid delivery systems is comprised of a flat non-circular orifice ridge adjacent to which a control plate having a planar control surface is proximally positioned to adjust the valve effective opening area and thereby the conductance of the valve. The length of the non-circular orifice ridge periphery is substantially greater than the circumference of a similarly sized circular orifice and therefore the realized effective opening area is also substantially greater despite having a similar footprint.

摘要： The present invention relates to a grease injection nipple coupled to a grease pipe such that the same can function as an opening/closing valve with regard to the corresponding grease pipe, the grease injection nipple being pushed against a nipple of a grease supply target and coupled thereto or separated therefrom. The grease injection nipple according to the present invention comprises a push body, a check valve, a nipple coupling portion, and a valve activation portion. The valve activation portion may operate such that, when the push body makes a primary movement in the forward direction, the check valve is opened and, when the push body makes a secondary movement in the forward direction after external force for the primary movement of the push body is released, the check valve is closed.

摘要： A solenoid valve includes a solenoid portion that moves a pin to one axial side and a nozzle portion including a valve body connected to one axial side of the pin. The valve body is driven by the pin and moves to one axial side to close a valve hole and urged by a spring and moves to the other axial side to open the valve hole. The spring is disposed in an annular space between a radial outer surface of a second valve body portion and a radial inner surface of a valve chamber, one axial side of the spring is in contact with a bottom surface of the valve chamber, the other axial side is in contact with a first valve body portion extending radially from an outer surface of the second valve body portion, and the spring urges the valve body toward the other axial side.

摘要： A liquid control valve including a body comprising an inlet port, an outlet port, and an interior chamber, the body defining a liquid passageway between the inlet and outlet ports. Also included is a plunger comprising a groove provided on an external wall, the plunger being configured to reciprocate within the interior chamber of the body between a first position where the valve is closed and a second position where the valve is open. Also provided is a sealing arrangement within the groove configured to seal between the plunger and the interior chamber of the body. The sealing arrangement includes a first sealing element on the external wall of the plunger and spaced apart from an inner wall of the internal chamber, and a second sealing element on the inner wall of the internal chamber and spaced apart from the external wall of the plunger.
