Duck-billed check valve

Номер: US20120192977A1

A duck-billed check valve includes a fitting tube, which receives a duck-billed tube fit therein. The duck-billed tube has a valve opening that is deformable for opening and an insertion opening. The insertion opening receives a liquid inlet tube formed in a lid of a waste liquid collection bottle to fit therein, whereby when the liquid inlet tube is fit into the duck-billed tube, the valve opening is compressed to deform and thus open. When the liquid inlet tube is separated from the duck-billed tube, the valve opening is not compressed and thus set in a closed condition. With such a deformed-to-open arrangement of the valve opening, when the waste liquid collection bottle is removed for replacement, liquid is prevented from leaking through the end of a pipe detached from the waste liquid collection bottle and the potential risk of infection of cleaning personal in cleaning liquid leakage is eliminated.

Принадлежит: Codman and Shurtleff Inc

A valve unit capable of being implanted in a patient and having adjustable performance settings, such as pressure settings and/or flow control, to regulate passage of a bodily fluid. A casing defines a port for the bodily fluid, and a valve mechanism positioned at the port includes a movable valve member. The valve unit further includes a rotor disposed at a first location in the casing and having an axle which turns about an axis of rotation. The rotor defines a plurality of arcuate, radially flat cam surfaces. Each cam surface occupies an arc about the axis of rotation. A spring arm unit is disposed at a second location in the casing having a cam follower arm in slidable contact with the cam surfaces of the rotor and having a resilient spring element applying a closing effect with the movable valve member to establish a performance setting for the valve unit. Sufficient rotation of the rotor to change the cam surface in contact with the cam follower alters the closing effect with which the valve member moves relative to the port and thereby alters the performance setting of the valve unit.

Принадлежит: Applied Materials, Inc.

Embodiments disclosed herein generally relate to a slit valve door assembly for sealing an opening in a chamber. A slit valve door that is pressed against the chamber to seal the slit valve opening moves with the chamber as the slit valve opening shrinks so that an o-ring pressed between the slit valve door and the chamber may move with the slit valve door and the chamber. Thus, less rubbing of the o-ring against the chamber may occur. With less rubbing, fewer particles may be generated and the o-ring lifetime may be extended. With a longer lifetime for the o-ring, substrate throughput may be increased. 1. A slit valve door , comprising:a first body;a second body that is separate from the first body and that is movable relative to the first body, the second body having a first surface and a second surface substantially perpendicular to the first surface;a bearing coupled between the first body and the second body;a first bellows coupled to the first body and the first surface of the second body; anda second bellows coupled to the first body and the second surface of the second body.2.

This invention concerns relievable normally closed check valves for use in conjunction with fluid delivery systems for medical patients, as well as methods for making and using valves. In the medical context, such valves function at very low fluid pressures, and include a multi-part valve body made from upper and lower housings capable of movement relative to each other that, when operably connected, dispose between them a compliant or deformable, resilient valve element normally biased in the closed position against a valve seat present on the inner surface of the upper housing. The upper housing also includes a lower housing seat. The inside surface of the lower housing contains or supports a structure that positions the valve element to engage the valve seat in the absence of fluid pressure above the valve's pre-determined cracking pressure. The valve's flow prevention function may be relieved in the absence of sufficiently pressurized fluid by causing the valve element to disengage from the valve seat, for example, by adjusting the valve body to distance the valve element from the valve seat. 1. A relievable one-way check valve , comprising:(a) a valve housing having a valve seat;(b) a valve element within the valve housing that is biased against the valve seat in a normally closed position but that opens when exposed to a pressure differential that meets or exceeds a rated cracking pressure for the valve; and(c) a valve relief feature that, when actuated a user, opens the valve to fluid flow at a pressure that is less than a rated cracking pressure for the valve.2. A valve according to claim 1 , wherein the valve relief feature claim 1 , when actuated claim 1 , causes change in a physical relationship between the valve seat and valve element claim 1 , resulting in fluid flow through the valve even if the pressure differential across the valve element is less than the rated cracking pressure for the valve.3.

Check valve assembly (′) for a shock absorber () comprising a housing (), said housing () comprising a first volume (), wherein a first pressure (P) prevails; a second volume (), wherein a second pressure (P) prevails; a fluid passage () between said first () volume and said second () volume; and a spool () movably arranged in said housing () for movement back and forth between an first position, in which a flow of fluid through said fluid passage () is allowed, and a second position, in which the spool () closes the fluid passage (). The check valve assembly further comprises a first biasing means () configured to bias the spool () towards the second position through at least first operational range (OR) of the spool () in which first operational range the fluid passage () is open. Also, the check valve assembly comprises a second biasing means () configured to bias the spool () towards the first position partly through a second operational range (OR) of the spool () in which second operational range (OR) the fluid passage () is closed. The first biasing means forces the spool from its open position at least to its closed position for closing the passage. 111100.

A self-closing dispensing valve is made of an elastic material and includes a valve head with a dispensing orifice, a circular peripheral retaining flange spaced apart from the valve head in an axial direction, and a connector sleeve integrally connected with the valve head on one end and the retaining flange on another end. The elastic material is a plastomer or a thermoplastic elastomer. The connector sleeve is substantially form stable. The valve head is connected to an upper end of the connector sleeve by a hinge portion that is U-shaped in cross section. The wall thickness of the hinge portion is smaller than the wall thickness of the connector sleeve and is staggered at the transition between the connector sleeve and the hinge portion. Alternatively, if the connector sleeve is omitted, then the valve head is directly connected to the retaining flange.
