摘要： A wearable EVD system having a ventricular catheter and transducer supported proximately to a patient's ear by a mount, such as supporting headband or ear clip. An adjustable orifice valve or a spring-loaded needle valve is used to control the amount of CSF that drains into a drip chamber suspended on the patient for periodic measurement and emptying into a similarly located drainage bag, thereby avoiding the need for an IV pole and allowing the patient more mobility without disrupting drainage of CSF.

摘要： The present invention is directed to a check valve 10, an injection assembly 60, and a beverage preparation machine 100, which is integrated in the injection assembly 60. The check valve 10 of the present invention is made of a body with a first fluid outlet 21, and a plug member 30 that is movable inside the body 20. The plug member 30 has a fluid inlet 32 and a second fluid outlet 31 into a first cavity 11, wherein the fluid can exercise a pressure on a first surface 381 of the plug member 30 opposing the first fluid outlet 21. The fluid pressure can overcome the force of an elastic element 40, which biases the plug member 30 into a closed position. If the force of the elastic member 40 is overcome, the plug member 30 is moved into an open position. In the closed position a fluid path from the cavity 11 out of the first fluid outlet 21 is closed, whereas in the open position said fluid path is open. To move the plug member 30 from its initial closed position to its open position, a fluid pressure on the first surface has to be equal to or larger than a predetermined threshold.

摘要： A relief valve assembly. The relief valve assembly has a housing that houses a sleeve element that surrounds a spool that has a spring guide disposed therein and is biased away from the spool by a spring. A fluid flow path is created from a valve exit of the assembly through the sleeve and spool via a series of openings, grooves and orifices in at least one position of the relief valve assembly. The fluid flow path acts to reduce pressure rise rate.

摘要： A combination check valve and pressure relief valve is provided for use in regulating the flow of fluid between a first fluid side and a second fluid side. The combination check valve and pressure relief valve includes a valve plug, a valve guide moveably positioned in relation to the valve plug, a valve stem engaged to the valve guide, a check compression spring attached to the valve stem and positioned between the valve guide and the valve plug, a valve seat carried by the valve stem, and a relief compression spring positioned between the valve seat and the valve guide. The valve guide is adapted to move the valve stem relative to the valve seat against the force of the relief compression spring to allow fluid to pass from the first fluid side to the second fluid side through a fluid flow passage formed between the valve stem and the valve seat. Furthermore, the valve seat, valve stem, and valve guide are adapted to move relative to the valve plug against the force of the check compression spring to remove the valve seat from an opening formed between the second fluid side and the first fluid side to permit fluid to pass through the opening.

摘要： This invention is an effective engine induction valve which provides a decrease in engine blowback while maintaining engine power. This valve uses a moveable member made from a heat-setting material, this member being bent into an elliptical curve when the member is in the closed position. This elliptical curve has an included angle at the edge of the member which opens toward the engine, this orientation being beneficial in reducing blowback. Using springs to limit the force attaching the moveable member to the valve body prevents unwanted buckling of this member when exposed to elevated temperature and fuel. An embodiment is described which provides a valve with a uniform frequency response at various operating conditions, especially different temperatures.

摘要： An air inlet valve assembly for a rotary scroll compressor is disclosed. The rotary scroll compressor includes stationary and orbiting scroll elements which are intermeshed and nested to form at least one spiraling compression pocket therebetween, a drive mechanism drives the orbiting scroll element in an orbit about the stationary scroll element, and an anti-rotation bearing device maintains the orbiting scroll element substantially non-rotational with respect to the stationary scroll element. The air inlet valve assembly supplies an uncompressed gas (e.g., ambient air) to the compression apparatus and prevents backward rotation of the orbiting scroll element when power to the drive mechanism is terminated. The air inlet valve assembly includes a valve piston positioned within an air intake channel leading to the suction region of the rotary scroll compressor, the valve piston having a first position blocking the air intake channel and a second position unblocking the air intake channel. A valve stem member is connected to a valve housing, the valve housing enclosed a valve cavity wherein the valve piston is located, the valve piston coacts with a valve seat formed on the valve housing, and stop surfaces are provided on the valve piston and the valve stem to limit movement of the valve piston toward the suction region of the rotary scroll compressor.

摘要： A compressor assembly is disclosed including a compressor mechanism mounted within a hermetically sealed housing. A cylinder block assembly, containing a plurality of reciprocating pistons within compression chambers, is covered by cylinder heads. The compression chambers include a discharge valve which permits compressed refrigerant to empty into a common discharge chamber. A pressure relief mechanism, formed by cylinder heads yieldably attached to the crankcase, is included within the compressor to eliminate damage caused by high pressure conditions such as slugging. Alternatively, pressure relief may be created in the common discharge chamber by a yieldably attached cage bearing or a valved port.

摘要： An inline check valve (10) has a valve body (12) with an enlarged diameter valve chamber (14) in which a cage assembly (44) is mounted. Cage assembly (44) has a cylindrical body (48) fitted about the outlet flow passage (18) and projecting in unsupported cantilevered relation within the valve chamber (14). The free end portion (56) of body (48) mounted a piston check valve member (50) thereon for relative reciprocal movement between open and closed positions. Upon a reversal of fluid flow, the entire rear face for the check valve member (50) is exposed to fluid pressure from the outlet flow passage (18), and the check valve member (50) immediately moves to closed position under the influence of spring (86) and fluid pressure. Cage assembly (44) may be inserted within and removed from the inlet fluid passage (16) upon removal of the inlet seat (36) and retainer (42).
