摘要： A dual union drain valve assembly has one or more reversible check valve inserts in the fitting(s) that are coupled to the drain valve body. The coupling of the fittings to the drain valve body is done using union couplings permitting the easy installation and/or reversal of the check valve insert(s). In addition, the union couplings permit removal of the dual union drain valve assembly from the surrounding plumbing system for service or replacement of the dual union drain valve assembly.

摘要： Not only a cylindrical weight is inserted with a clearance around an outside of a first axis part or a second axis part that extends opposite to the first axis part and is movable freely in an axial direction but also an annular seat surface on which the cylindrical weight is able to be seated by self-weight is provided with a governor valve. A projecting part(s) is provided with only a part in circumferential direction of one of the annular seat surface and a lower end surface of the cylindrical weight. The cylindrical weight is made sure to be supported on the annular seat surface in an inclined state from an upright posture by contact of the projecting part(s) with the other of the annular seat surface and the lower end surface of the cylindrical weight.

摘要： A high-pressure valve assembly is provided. The high-pressure aerator valve assembly includes an outer housing with front and back ends terminating a central passageway; a movable valve member having a one-piece unitary metal construction slidably engaged within the central passageway in the outer housing, the valve member having an enlarged head termination sealing the front end of the passageway. The assembly also includes a spring-loaded spring guide member also having a one-piece unitary metal construction which is fixed within the central passageway in the outer housing intermediate the front and back end and a wave spring having a predetermined spring constant for supplying spring tension to keep the moveable valve member sealed. Also included are operational sensors which include a linear shaft displacement counter for counting the number of times the valve member opens and closes; a vibration sensor, or accelerometer, for measuring vibration, a temperature sensor and/or an air pressure sensor. The assembly also includes externally accessible on-board memory for storing sensing data.

摘要： A phaser valve for a piston and cylinder assembly helps to keep a pair of pistons in phase with each other. The phaser valve includes a poppet which is slidable between opposing seats of a valve housing. The poppet includes a head and a stem, both the head and the stem having concave portions which facilitate the flow of hydraulic fluid across the valve. The poppet head has two generally conical ends, so that the head makes a fluid-tight seal with a seat when the head is urged towards either seat. Due to its construction, the phaser valve may be built to fit within a very small space, while still allowing a substantial flow of fluid when the head is not in abutment with one of the seats.

摘要： A fuel filter device includes a bag-shaped filter member filtering fuel that is drawn into a fuel pump, an inner frame member retaining the filter member in an expanded state, and a mounting member connected to the inner frame member and serving to communicate an internal space of the filter member with an outside. A valve chamber is defined by the inner frame member and the mounting member, and a check valve serving to prevent backflow of fuel is disposed in the valve chamber. The check valve includes a flat-plate shaped valve body having elasticity. The check valve opens against its weight when the fuel pump is operated, and the check valve closes due to its weight when the operation of the fuel pump is stopped.

摘要： Adaptive stimulation systems combine impulse-generated swept-frequency stimulation vibration with cyclically-varying hydraulic pressure to provide adaptive down-hole stimulation. Swept-frequency stimulation vibration arises from cyclical shifts of the power spectral density (PSD) of each stimulator's vibration (via closed-loop control of rebound cycle time). PSD's are adjusted for resonance excitation, fracturing and/or analysis of geologic materials at varying distances from a wellbore. And closed-loop control incorporates backscatter vibration from stimulated geologic material. Stimulators can be arranged singly or in spatial arrays of multiple stimulators, each stimulator generating vibration in bursts comprising a plurality of vibration frequencies. Timed signals from a programmable controller affect directional propagation of combined vibration wave fronts from a stimulator array. As fracturing proceeds to smaller (e.g., proppant-sized) fragments having higher resonant frequencies, PSD's are up-shifted, increasing relative stimulation vibration power in higher frequencies. Progressive stimulation is thereby optimized, facilitating plain-water (or liquefied propane) fracs with self-generated proppant.

摘要： Valve arrangement for ensuring different amount of medium flow-through comprising at least two chambers (6,7) separated by a limiting wall (3) provided with a through-opening (1). An insertion piece (2) in the through-opening (1) is able to move transversally and the cross-section of its elongated middle portion (4) corresponds to that of the through-opening (1). At least at one end of the insertion piece (2) a closing head (5) is provided. A form-fitting (8) between the closing head (5) and the limiting wall (3) ensures a first closed state thereby a first amount of flow-through from a chamber (6) being on one side of the through-opening (1) to the chamber (7) being on the other side of it when the longitudinal movement of the insertion piece (2) is limited as the closing head (5) abuts against the limiting wall (3) at the through-opening (1).

摘要： A modular check valve system for providing back pressure to a fluid flow having a housing with a seating end, a receiving end, a housing annulus, and a housing sealing surface. The modular check valve system can also have at least one cartridge insert fluidly connected to the housing. The cartridge insert can have a poppet engaging a cartridge housing sealing surface, a pair of O-rings positioned on the cartridge housing, and a rod secured to the poppet. The rod is configured to move the poppet from a sealed position to an open position. A spring guide with spring is disposed around the rod. A compression adjustment device is connected to the first rod opposite the spring guide to apply force to the rod sealing the poppet against the cartridge housing sealing surface and creating fluid back pressure in the housing annulus when the spring is decompressed.

摘要： A sleeve (10) allows flow against gravity of molten metal into a casting mold. The sleeve has a sleeve body (20) with a longitudinal axis that defines a flow conduit for the metal. A check valve (30) is positioned in the flow conduit, arranged for limited axial movement in the sleeve between a closed position and an open position, although it is operatively positioned to be in the closed position in the absence of the pressurized metal. The check valve has a spool (32) with an internal flow conduit, a top end of the conduit blocked by an end cap (40). Flanges (36, 38) on the spool provide the limited axial movement in the sleeve. When lifted into the open position, metal flows into the spool flow conduit and through a porous structure of the spool, causing laminar flow and filtering inclusions.
