| 6 | Rotary Ceramic Valve | US14138873 | 2013-12-23 | US20140183395A1 | 2014-07-03 | Robert C. Popke; William S. Sankey |
| A rotary ceramic tube valve is disclosed. The valve may have an outer shell and an inner ported cylinder which move in relation to each other of open and close ports on the valve. By turning the inner ported cylinder in relation to the outer shell, different orifices in the outer tube may be opened or closed. By coating the inner surface of the outer tube and the outer surface of the inner ported cylinder with a ceramic coating, friction in the valve may be reduced resulting in longer life, less heat generation, tighter tolerances and more reliable long term operation. Further, inner rotor 200 may also have cylindrical pressure balancing seals and related pressure communicating paths that provide counterforce to reduce stress on the bearings. | ||||||

| 8 | Method for preventing internal pressure rise and its device in mixture water plug of hot water and cold water | JP25420485 | 1985-11-12 | JPS61112872A | 1986-05-30 | KITAMURA YOSHIAKI; NOMURA HITOSHI |
| PURPOSE:To prevent rise of internal pressure due to heating in a water supply room by releasing water little by little to a flowing room from a variable relief groove provided on a variable still water face around the flowing room. CONSTITUTION:When a lever handle 24 is turned to the H direction, a flowing room 18 of a movable valve sheet 20 is communicated only to a hot water valve port 14 of a fixed valve sheet 17 to supply hot water. This time, if hot water supply is continued, the flowing room 18 and a water valve port 15 are communicated by a variable relief groove 19 provided on the movable valve sheet 20 and a still water face 21 of the fixed valve sheet 17. The water heated by hot water and begun to expand in a water supply room 5 is discharged from the relief groove 19 into the flowing room, and internal pressure rise in the water supply room 5 due to connecting hot water supply can be prevented. | ||||||

| PURPOSE:To achieve reliable work and to improve assembling work by fitting an auxiliary operating board idly to a rotary shaft of main valve then inserting the main valve rotary shaft through a bearing fitted in the groove of cover to use as an upper limit stopper for main valve and auxiliary operating board. CONSTITUTION:A rotary shaft 28b is projected from main valve 28 while a bearing 44 is engaged with bearing groove section 41a in the cover 41. Said shaft 28b is inserted through a bearing 44 while inserted with an auxiliary operating board 30. Auxiliary operating board 30 is holding a ball valve 31 in the containing section 30a where the communication hole 29a through the seat 29 is sealed by the ball valve 31 and when moving main valve, said hole 29a is opened to cancel pressure difference. Upward motion of main valve and auxiliary operating board is limited by the bearing 44 to provide reliable and safe rotation. | ||||||

| 本サーボ弁は回転プレート弁体であり、内部に形成されたキャビティで弁ポートが接続されるものである。弁体のキャビティは弁体の両側面に左右対称に形成され、左右対称のキャビティは、補強された網により分離される。網のスルーホールにより左右対称のキャビティを繋げる。コントロールオリフィスは弁体キャビティのいくつかのエッジ及び弁体周辺の固定したキャビティのエッジの間に形成され、そこの目的で適切に設計される。弁内部の流路は弁体のキャビティと周辺部品により形成され、クロスセクションエリアの十分な流れを生む。コントロールオリフィスは弁体の両側で対に形成され、その領域を広げ、流力によりラテラルバランスを得る。弁体の角部分は、両側で同じ圧力を受けることにより静的なバランスを得る。回転運動により短いストロークの直線駆動または比較的大きいコントロールオリフィスを生成する。キャビティを備えた薄い弁体は低いイナーシャと高い反応速度を得られる。 | ||||||

| 17 | Actuator apparatus with internal tubing and anti-rotation mechanism | US14189627 | 2014-02-25 | US09458947B2 | 2016-10-04 | David Anthony Arnold; Daniel Martin Adams |
| Fluid valve actuator apparatus having internal tubing and anti-rotation features are disclosed. An example actuator apparatus includes an actuator casing and a diaphragm plate disposed within the actuator casing. The diaphragm plate defines a first pressure chamber and a second pressure chamber opposite the first pressure chamber. A yoke couples the actuator casing to a fluid valve. The yoke includes a first internal fluid passageway in fluid communication with atmosphere and a second internal fluid passageway to receive a control fluid from a controller. A tube fluidly couples the first or second internal fluid passageway to the first pressure chamber via an opening in the diaphragm plate. The tube also prevents the diaphragm plate from rotating relative to the actuator casing. | ||||||
| 18 | METHOD AND APPARATUS FOR READMITTING AIR INTO AIRTIGHT CONTAINERS | US14615962 | 2015-02-06 | US20160230905A1 | 2016-08-11 | Thomas Calvin Cannon, JR. |
| The present invention is a method and apparatus for readmitting air into vacuum containers, such as canning jars, by incorporating a flexibly-mounted check valve in the container lid or body, and sandwiching an elastomeric seal member, such as an O Ring, between the check valve and the vacuum container's lid or wall. The check valve is flexibly mounted to the airtight container by a retainer member that permits the check valve to move vertically and horizontally and compresses the elastomeric seal member sufficiently to prevent leakage. Air is readmitted into the vacuum container by applying a force to the check valve that sufficiently decompresses a segment of the elastomeric seal member to cause leakage. The displacement force on the check valve may be applied by hand, without using any tools. | ||||||

| A method and an apparatus for detecting an opening and closing of a pilot operated solenoid valve provided in a hydrogen tank can open or cut off a channel of hydrogen gas supplied to a stack. The method includes receiving a valve opening command; determining whether valve driving input/output signals responding to the valve opening command are abnormal; checking a pressure inside a high pressure hydrogen pipe when it is determined that the valve driving input/output signals are normal; and outputting a valve opening signal when the checked pressure satisfies a valve opening condition. | ||||||
| 20 | Control valve | US610232 | 1975-09-04 | US4029293A | 1977-06-14 | Raymond Richard Meysenburg |
| A manually operable valve for controlling the displacement of a main pump in a hydrostatic transmission controls the quantity of fluid flow to the main pump for low speed operation of the transmission and controls the pressure of the fluid flowing to the main pump during periods of high speed operation of the transmission. The valve includes a pressure chamber acting to substantially balance forces on the valving element to obtain low-effort operation of the control plunger regardless of the position of the element and to automatically close the valve upon a failure in the control linkage for the plunger so that in the event the operator loses control of the valve through linkage failure all power to the transmission is cut off. | ||||||
