SPRING-LESS CHECK VALVE FOR A HANDPIECE

A hand piece for a surgical instrument is provided. The handpiece has an inlet (22), a chamber (with upstream and downstream portions), a flow control member, a pulse engine (26), and an outlet. The inlet communicates with the upstream portion (37) of the chamber. The downstream portion of the chamber communicates with the engine. The engine communicates with the outlet (24). In a closed position of the member, flow from the inlet moves the member to the open position thereby allowing flow through the flow path. In the open position, pulses from the engine move the member to the closed position before pulses from the pulse engine can flow through the flow path, thereby preventing flow through the flow path.

VALVE CAGE FOR A PUMP

A valve cage device is adapted for use with a subsurface pump or the like. The valve cage includes a housing and an insert. The insert includes a cradle, a plurality of angled ribs, and a base. In one embodiment, the insert may also include an extended nose region. A ball and seat may be positioned in the valve cage.

This eliminates violent action of the ball, thereby obviating a need for a hard liner to be included in the valve cage. A port in the cradle allows fluid to pass therethrough when the ball has been released from the cradle. The angular configuration of the ribs provides for a more laminar flow of fluid compared with prior art valve cages, thereby providing improved passage of fluid through the valve cage. The base may include an angled hook or lip that creates a tight seal, thereby preventing fluid from washing ...

Check valve

Ball check valve

A pressurized nuclear reactor having an instrument assembly sheathed in a metallic tube which is extended vertically upward into the reactor core by traversing a metallic guide tube which is welded to the wall of the vessel. Sensors in each instrument assembly are connected to instruments outside the vessel to manifest the conditions within the core.

566,073. Jointing by stamping. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, W. H. J. May 6, 1943, No. 7210. [Class 83 (iv)] [Also in Groups XXVIII and XXIX] Relates to dished washers or discs for use in or on tubes or like members to exert a gripping engagement upon flattening and consists in a form that compensates for variations in the size of the tube &c. and consists in dividing the edge that engages the member into a number of sections each having a limb extending circumferentially to bear resiliently against the member. The washer 10 may comprise radial arms 12 extending from a central disc 11 and extended circumferentially at 13a, 13b. The washer is dished as shown in Fig. 2, and the limb 13a, 13b is initially curved to a greater radius than that of the member in which the washer is to be inserted, for example, a piston 18 having a valve 16 that is seated by a light spring 15 that abuts the washer 10 retained in a counterbore 19 against a shoulder 20. In other examples, the washer may be expanded into a groove in the outer member and is shown as closing a chamber for retaining the ball of a ball valve, and as securing a closure member in a tube. In another form the radial arms 12 are formed with eyes 12a, Fig. 6, to impart additional elasticity or they may be formed corrugated or sinuous. In other forms, the limbs extend from one side of the arms only and all in the same direction, or arms such as 13a, 13b extend from the vertices of a triangular centre portion.

Volumetric pump/valve

A volumetric pump for administering intravenous fluids to a patient comprises a housing having an elongate cavity therein with an open and a closed end. A resilient sheet of material having a centrally-located aperture covers the open end, and a pump shaft is slidably disposed through the aperture to form a sphincter seal therebetween. An inlet conduit leading from a fluid source (an IV bag) passes through the housing into the cavity near the open end thereof, and an outlet conduit leading to a fluid sink (the patient) passes through the housing from the cavity near the closed end thereof. The shaft is driven back and forth in reciprocating motion inwardly and outwardly of the cavity to produce, respectively, a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.

Flow-responsive diverting valve

A flow-responsive diverting valve is particularly useful with pressure washers of the type having a water pump coupled to an internal combustion engine equipped with a pull-rope starter. The valve provides an "easy-start" feature and has a valving chamber and a fluid inlet and two fluid outlets. A magnet is fixed on the valve body and when fluid flows into the inlet at the low flow rate occurring when operating the starter, a valving device, e.g., a check ball, is restrained by the magnet. When fluid flows into the inlet at a higher flow rate (as when the engine is running and the pump is delivering water at a substantial rate), the device closes the first outlet and diverts water to the second outlet. A method for operating a pressure washer includes magnetically restraining the valving device away from the first outlet while operating the starter and then running the engine, thereby urging the device to close the first outlet.

Maximum operation angle single plug and puppet type retention valves

A check valve assembly is disclosed wherein a valve closure means includes a guide means and a connector means as a composite member for use in a pipline or conduit inclined to the vertical. The mass of the composite member relative to the angle of inclination and the coefficient of friction between the internal surface of the valve body and the external surface of the guide means is such that there is no risk of valve "jamming" action which would block operation of the valve. In addition the guide means ensures symmetrical fluid flow whereby the valve operates positively and rapidly eliminating chatter and erratic travel during the course of opening and closing when fluid flow is reversed.
