| 101 | Valve assembly for high pressure water shut-off gun | EP91300311.7 | 1991-01-16 | EP0438285A2 | 1991-07-24 | Pacht, Amos |
A shut-off valve assembly (10) in a very high pressure water gun is provided with a valve member (42) between a pressure chamber (17) and an outlet chamber (19) which produces a quick pressure induced snap-off action just before closing which securely seats the valve member against leakage and erosion. Shortly after cracking the valve to an open position the pressure induced force is relieved and the regular biasing spring (56) offers the only closing force. An improved high pressure seal (98) is configured to seal with a short stem contact area designed to significantly reduce friction. A special safety bleeder valve bleeds to atmosphere independent of starting pressure. |

Um mit minimalen Umschaltkräften auskommen zu können, ist jeweils einer der zusammengehörigen Dichtbereiche am Schaltkörper (5, 5ʹ) bzw. am Ventilgehäuse (3, 3ʹ) eines Zweistellungs-Sitzventils in Form einer umlaufenden Schneide (8) mit im Querschnitt kleinen Kantenradius ausgeführt, was nur sehr geringe Kräfte zum Dichthalten des Ventils erfordert. Insbesonders im Zusammenhang mit einer druckausgeglichenen Bauweise ergibt sich damit die Möglichkeit sehr geringe Steuerenergien maximal zu verstärken. |

| A high force-gain valve (10) including a housing (12) having first (14) and second openings (16) therein, a fluid diverter (24) fixed in position within the housing and aligned with the second opening, a translatable gate (28) closely surrounding the diverter and having a sealing edge (30) which in the closed position seats against the portion of the housing adjacent the second opening, and a positioner for translating the gate between open and closed positions. The gate is hollow, its interior being in fluid communication with the interior of the housing, and has a beveled sealing edge, exposing most of the sealing edge to the fluid pressure within the housing, and is therefore force balanced. The force balancing permits the gate to be easily and quickly translated and positioned between the open and closed positions. | ||||||

| Vanne à gain de force élevé (10) comprenant une enceinte (12) pourvue d'une première (14) et d'une deuxième (16) ouvertures, un déviateur de fluide (24) fixé en position à l'intérieur de l'enceinte et aligné avec la deuxième ouverture, une porte pouvant effectuer une translation (28) entourant immédiatement le déviateur et possédant un bord d'étanchéité (30) lequel, dans la position fermée, s'appuie contre la partie de l'enceinte adjacente à la deuxième ouverture, et un organe de positionnement servant à déplacer la porte entre les positions ouverte et fermée. La porte est creuse, son intérieur étant en communication de fluide avec l'intérieur de l'enceinte, et possède un bord d'étanchéité biseauté, soumettant la plus grande partie du bord d'étanchéité à la pression de fluide à l'intérieur de l'enceinte, et est par conséquent équilibrée par rapport à la force. L'équilibrage de force permet à la porte d'être déplacée aisément et rapidement entre les positions ouverte et fermée. | ||||||
| 107 | High pressure regulator valve | EP83305798 | 1983-09-28 | EP0104944A3 | 1984-12-12 | Pacht, Amos |
A pressure regulating valve for controlling pressure in high pressure hydraulic circuits includes a closure member 36 with an integral control piston 33 and a conical seating surface 38 cooperable with a complementary surface on a seat member 39. The valve closure member is biased in the closed position by an actuating mechanism including a pressure gas piston 88 and cylinder 72 arrangement utilizing a flexible diaphragm 90 for sealing the actuator pressure chamber 96. The effective cross-sectional area A3 of the control piston is large enough to minimize the differences in cross-sectional areas on the closure member exposed to pressure fluid between the valve closed and valve open positions whereby a minimum variation between the valve opening pressure and the control pressure is experienced. The increase in pressure in the actuator pressure chamber 96 resulting from movement of the valve from the closed to open positions substantially offsets the change in effective face areas of the closure member to further minimize the difference between the valve opening pressure and the steady state regulated pressure. |

| Le dispositif de commande hydraulique comporte un bâti (1), un tiroir de distribution (2) coulissant dans un perçage (10) du bâti et un anneau de commande (3). Des conduits de raccordment (A, B, P, T) peuvent être connectés entre eux ou bloqués mutuellement selon la position du tiroir de distribution (2) en le déplaçant axialement. Dans l'espace annulaire (35) situé entre un segment du perçage (10) du bâti et le tiroir de distribution (2) est prévu un anneau de commande (3) disposé coaxialement au tiroir (2) et monté coulissant sur celui-ci. Dans le perçage (10) du bâti et sur le tiroir de distribution (2) sont prévus, espacés axialement, des sièges de soupape (11, 12; resp. 20, 21) l'anneau (3) de commande présentant des surfaces internes (33, 34) et externes (31, 32) coopérant avec les sièges de soupape. Un canal (24) est pratiqué dans le tiroir de distribution entre ses deux sièges de soupape (20, 21), ce canal pouvant être obturé d'un côté ou de l'autre selon la position de l'anneau (3) de commande. Celui-ci est maintenu dans la position de fermeture correspondante par la pression du milieu; la commutation est indépendante de la pression vu que le tiroir de distribution n'est soumis à aucune force axiale de la part du milieu (fig. 1 et 2). | ||||||

| 118 | Balanced valve trim and method of reducing stem forces on a valve stem | US14974103 | 2015-12-18 | US10094488B2 | 2018-10-09 | Trenton Frank Jackson |
| Valve trim for a valve includes a valve plug having one or more balance ports located along the outer surface of a tapered nose portion of the valve plug. Each balance port is located to be downstream of the throat and spaced from the tip of the tapered nose portion of the valve plug. The valve trim may be use, for example, in a high recovery angle body valve. A high recovery valve with the valve trim may have better recovery performance as well as a smaller spike in stem force through the choked flow transition point. A method of reducing stem forces on a valve stem of sliding stem valve is also provided. | ||||||

| A valve may use fluid pressure to provide bistability to the valve by creating two regions that experience different pressures on one surface of the valve. The two regions may change in size relative to each other as the surface approaches another surface thus changing the combined pressures experienced by the regions. A velocity of fluid flow may increase as it passes one of the regions thus reducing pressure to that region. Additionally, an eddy current may form adjacent another one of the regions thus reducing pressure to that region. Consequently, the valve may be urged open when open and urged closed when closed. | ||||||

| An electropneumatic proportional flow control device improves electropneumatic control of pneumatically operated valves. A single integrated valve incorporates a proportional valve component in operational and physical coordination with a pressure regulator valve component. The flow path of fluid is initially passed through the regulator component whereby pressure is regulated to within a manageable range for operation of a balanced type proportional valve component. | ||||||
