摘要： To provide a control valve (V) capable of stably removing air.
The control valve (V) includes a valve body (46); a spool hole (47) formed in the valve body (46); a spool (45) slidably fitted in the spool hole (47); a pilot chamber (57) into which a pilot fluid to actuate the spool (45) is led; a discharge passage (51) to discharge a hydraulic fluid to an outside of the valve body (46); a spiral groove (67) to communicate with the discharge passage (51), the spiral groove (67) being formed in a spiral shape on an outer periphery of the spool (45); and at least one axial groove (72) to cause the pilot chamber (57) and the spiral groove (67) to communicate with each other, the axial groove (72) being formed along an axial direction of the spool (45) on an inner surface of the spool hole (47).

摘要： A device (501) for controlling the flow of a fluid through a conduit from an upstream side of the device to a downstream side of the device. The device (501) includes an upstream valve casing defining an inlet (508), a downstream valve casing defining an outlet aperture (510), and a valve core secured between the upstream valve casing and the downstream valve casing. The valve core includes a housing (520) defining a control volume. A valve member is mounted on the housing (520) and positioned on the upstream side of the outlet aperture (510), the valve member being arranged to move reciprocally to selectively open and close the outlet aperture (510), thereby controlling flow of the fluid through the outlet aperture (510). A magnet (580) is embedded within the valve member. A position sensor (572), including a magnetic field sensor (582), determines the position the valve member.

摘要： A reversible electromagnetic valve (100) is provided, which includes a valve seat (10) having a valve port (11), a slider (20) slidably connected to the valve seat (10), and a driving member (30). The driving member (30) can drive the slider (20) to move in contact with the valve seat (10) to use a sealing surface (22) of the slider (20) to selectively block the valve port (11). The sealing surface (22) of the slider (20) has a sealing point (21); the sealing point (21) is provided corresponding to a limit position of an edge of the valve port (11) of the valve seat (10), such that when the slider (20) drives the sealing point (21) to cross the valve port (11), the sealing surface (22) of the slider (20) can block the valve port (11); and under action of a pressure difference, a position where the sealing point (21) of the slider (20) is located is not lower than a plane where the edge of the valve port (11) is located.

摘要： Die Erfindung betrifft ein medizinisches Drucktastenventil (1) mit einem Ventilgehäuse (2), einem in dem Ventilgehäuse (2) ausgebildeten Strömungskanal (3) sowie mit einem Ventilkolben (4), der zwischen einer den Strömungskanal (3) freigebenden und einer den Strömungskanal (3) verschließenden Position verlagerbar im Ventilgehäuse (2) angeordnet ist, wobei der Ventilkolben (4) mit einem am Ventilgehäuse (2) gelagerten, über mindestens ein Federelement (13) federbelastetes Druckelement (9) in Wirkverbindung steht und der Ventilkolben (4) über das federbelastete Druckelement (9) in die den Strömungskanal (3) verschließende Position vorgespannt ist und das federbelastete Druckelement (9) in mindestens einer Position arretierbar ist, in der der mit dem Druckelement (9) in Wirkverbindung stehende Ventilkolben (4) den Strömungskanal (3) zumindest teilweise freigibt. Um ein medizinisches Drucktastenventil (1) zu schaffen, das eine einfache und ermüdungsfreie Einhandbedienung ermöglicht, wird erfindungsgemäß vorgeschlagen, dass in Richtung der Längsachse (10) des Ventilgehäuses (2) betrachtet am Ventilkolben (4) mit Abstand zueinander zwei Verschlusskörper (15 und 16) ausgebildet sind, die mit entsprechenden Ventilsitzen (17 und 18) zusammenwirken.

摘要： A valve assembly includes a valve body having an inlet port and an outlet port, the valve body also having a valve chamber extending between the inlet port and the outlet port, a pair of seals each being located on opposing ends of the valve chamber; and a reciprocating piston extending into the valve chamber and movable between a closed position extending through the pair of seals and an open position extending only through one of the pair of seals, wherein the inlet port is fluidly connected with the outlet port when the piston is in the open position. A method of using the valve assembly is also disclosed.

摘要： The invention relates to a distribution valve for use in the feed or return of a medium circuit, comprising a housing (1) that forms the feed or return conduit, a branch conduit (2) branching off the housing (1), and an adjusting unit (3) for adjusting the flow rate through the branch conduit (2), said adjusting unit being separate from the housing (1) and being arranged on the housing (1) opposite the branch conduit (2) and extending through the housing wall. The adjusting unit (3) comprises an adjusting spindle (4) the axial position of which relative to a component (5) of the adjusting unit (3) connected to the housing (1) can be varied by rotation, thereby varying the flow rate. The valve is designed such that an axial movement of the adjusting spindle (4) relative to the component (5) towards the branch conduit (2) results in an increase in the flow rate through the branch conduit (2). The valve according to the invention further comprises adjustable stop means by means of which an axial movement of the adjusting spindle (4) relative to the component (5) towards the branch conduit (2) can be limited in a defined axial position when a first stop face (7) connected to the adjusting spindle (4) abuts a second stop face (8) connected to the housing (1), in order to limit the maximum adjustable flow rate through the branch conduit (2). The invention provides in a cost-effective manner distribution valves that are compact and have a simple design and the flow rate limitation of which, once adjusted to a certain value, remains the same even despite temporary shut-off or temporary reduction of the flow rate.

摘要： A motion conversion device including a body, a first double-acting cylinder movable along a first axis and a second double-acting cylinder movable along a second axis angled relative to the first axis. The body includes several bores which form a closed circuit and house the first and second double-acting cylinders. Movement of the first double-acting cylinder along the first axis hydraulically or pneumatically pushes the second double-acting cylinder along the second axis. Also disclosed is a valve incorporating a motion conversion device with angled double-acting cylinders for moving a closure member between an open position and a closed position, and a method for opening and closing a valve by way of angled double-acting cylinders.
