Trip cock valve for a brake system on a rail car

A trip cock valve for a brake system on a rail car includes a valve body that defines an inlet, a chamber downstream from the inlet, and an outlet downstream from the chamber. A piston is inside the chamber. A valve member operably connected to the piston has a first position that prevents fluid flow through the outlet and a second position that permits fluid flow through the outlet. A lever is operably engaged with the valve member to move the valve member from the first position to the second position. A valve position indicator downstream from the inlet is in fluid communication with the inlet when the valve member is in the second position.

Fuel cutoff valve

A fuel cutoff valve has: a valve mechanism that cuts off a communication between a fuel tank and a canister; an upper space defined above the valve mechanism; a tube body that has a tube passage to be communicated with the upper space and introduces a fuel gas to the canister; a retaining chamber defined by a first fuel shielding portion and a second fuel shielding portion to retain a liquid fuel stored in the upper space; a liquid reservoir portion defined between the tube body and the first fuel shielding portion to store the liquid fuel flowing out of the retaining chamber; and a communication portion through which the retaining chamber communicates with the liquid reservoir portion; wherein the communication portion is formed at a position deviated from the tube body so as not to overlap the tube body, when the tube body is seen in its axial direction.

증기 벤트/팁핑 밸브는 캐니스터로 쪽으로의 증기 벤팅과 필러 튜브 쪽으로의 증기 재순환을 제어하기 위해 블리드(bleed) 유동의 압력차에 응답하여 그것을 통해 블리딩하는 다이어프램을 갖는다. 딥 튜브는 딥 튜브를 폐쇄하고 다이어프램 쪽으로의 증기 유동이 블리딩되는 것을 방지하기 위해 탱크 내의 연료 상승을 야기함으로써, 재순환 라인을 고갈시키며, 필러 내에 진공을 발생시키고 노즐 차단을 초래하도록 노즐을 배출시킨다. 변형적으로, 플로트 작동식 차단 밸브는 딥 튜브 및 증기 벤트 챔버 입구 내에서 사용될 수 있다. 차단 밸브는 팁핑/롤오버 보호를 제공하기 위해 플로트 밸브를 폐쇄하기 위한 관성 부재를 포함할 수 있다. The steam vent / tipping valve has a diaphragm that bleeds through it in response to the pressure difference of the bleed flow to control steam venting towards the canister and steam recirculation towards the filler tube. The dip tube closes the dip tube and causes a fuel rise in the tank to prevent bleeding of the vapor flow towards the diaphragm, thereby depleting the recirculation line and draining the nozzle to generate a vacuum in the filler and cause nozzle shutoff. Alternatively, float operated shutoff valves can be used in the dip tube and the vapor vent chamber inlet. The shutoff valve can include an inertial member for closing the float valve to provide tipping / rollover protection.

Safety and venting valves and cap for fuel tanks carried on vehicles

A tank venting, pressure and temperature relieving, and spill preventing valve for fuel tanks. The valve has a spin chamber (94), having generally circular cross sections and at least one side wall inlet opening (106) that is tangentially directed with respect to the circumferences of the cross sections. There is a circular outlet (80) at a normally upper and open end of the chamber. The chamber cross sections decrease in diameter upwardly of the inlet opening to below the outlet opening whereby gas venting through the chamber spins a light weight, buoyant ball (90) around the chamber so as to prevent the ball from closing during venting. The ball valve is adapted to be lifted to seat (88) on the outlet to close it when liquid enters the chamber to a predetermined level. A heavy ball (92) in the chamber holds the light weight valve ball on the seat when the chamber has been tilted a predetermined amount. There is a second heavy ball (84) externally of the chamber adjacent the outlet opening and adapted to move the light weight valve ball off the seat when the liquid is below a predetermined level and the chamber is not tilted, so that the outlet will be open for venting.

Cargo tank relief valve with sudden surge protection

The relief valve assembly has a spring-loaded poppet valve that vents the interior of a transport tanker to the atmosphere when gaseous pressure within the tank exceeds a predetermined limit. Sudden surge protection from a pressure spike created by liquid within the tank during the instant that the tank strikes the ground during accidental roll over is provided to keep the poppet valve closed during the surge condition. A reaction piston having one face that counteracts the face of the poppet valve is exposed to pressure within the tank simultaneously with the poppet valve, but the counteracting effect of that surface is normally overcome by a neutralizing chamber on the opposite side of the reaction piston which is likewise exposed to the interior of the tank. While gaseous pressure can reach all working surfaces of the valve essentially at the same time during gradual, progressive pressure buildup, in a sudden surge situation the liquid is restricted by port means from instantaneously entering the neutralizing chamber so that the reaction piston instead holds the poppet closed at this time. Once the initial liquid surge has passed, pressure within the tank can gradually enter the neutralizing chamber to allow the poppet valve to open in the usual manner if pressure exceeds the predetermined limit.

Vent tube means for a cryogenic container

A vent tube having a first branch and a second branch for use in a cryogenic container through which the interior of the container is communicated to the atmosphere. The cryogenic container is adapted to receive a fixed volume of cryogenic fluid at a uniform temperature and density. In a filling operation, the first branch of the vent tube contacts the cryogenic fluid and carries a portion of the fluid to the atmosphere to inform an operator that the capacity of the container has been reached. After the container is filled, the temperature in the stored cryogenic fluid rises. As the temperature changes, distinct stratified layers of fluid of different densities and temperatures can be measured in the container. The change in temperature causes the cryogenic fluid to expand and submerge the adjacent first branch of the vent tube. Thereafter, the second branch, which is located at the gravitational top of the container, provides a flow path to the atmosphere for the top layer of cryogenic fluid to assure that the higher density cryogenic fluid is retained in the container means.
