摘要： An air valve is disclosed suitable for relieving a vacuum in a pipe and preventing the escape of fluid therefrom. The valve includes a body having an inner chamber, an air inlet with inner and outer concentrically spaced valve seats, an opening for cummunicating the chamber witha pipe, and a stationary guide element. A valve element is displaceably mounted in the chamber and is normally urged to a closed position while being shiftable to an open position in response to a vacuum in the pipe. The valve element includes an annular disc of elastomeric material, and a hub mounted for axial movement along the guide element. The hub includes holes communicating the opening with the chamber and with an inner side of the disc when the valve element is in its open and closed positions. Thus, a vacuum at the opening is transmitted through the holes to the inner side of the disc to urge the disc open, and the absence of a vacuum or positive pressure, at the opening causes the disc to close. The hub includes a flange upon which an inner edge of an outer disc side sits usuch that the disc is cantilevered outwardly from the hub. This flange terminates short of the inner valve seat such that inthe valve-closed position, the outer disc side sealingly engages the inner and outer valve seats to prevent escape of fluid from the opening.
摘要翻译： 公开了一种适于减轻管道中的真空并防止流体从其中逸出的空气阀。 阀包括具有内室的主体，具有内和外同心间隔开的阀座的空气入口，用于将腔室与管道共同使用的开口以及固定导向元件。 阀元件可位移地安装在腔室中，并且通常被推动到关闭位置，同时响应于管道中的真空而能够移动到打开位置。 阀元件包括弹性体材料的环形盘，以及安装成沿导向元件轴向运动的轮毂。 当阀元件处于其打开和关闭位置时，毂包括将开口与腔室连通并且与盘的内侧连通的孔。 因此，开口处的真空通过孔传递到盘的内侧，以促使盘打开，并且在开口处不存在真空或正压使盘关闭。 轮毂包括凸缘，外盘侧的内边缘位于该凸缘上，使得盘从轮毂向外悬伸。 这个凸缘终止于内阀座之外，使得在阀关闭位置，外盘侧密封地接合内阀座和外阀座，以防止流体从开口逸出。

摘要： A pressure relief system for an aerosol dispenser utilizing resilient flexing rings or gaskets arranged in sealing relationship relative to vent ports and/or relief passageways so that, at a predetermined pressure, the force of the propellant and product within the aerosol dispenser acts outwardly against these flexing members to break the seal. Uniquely, the same vent ports and/or relief passageways may be used to pressure fill the aerosol dispenser. In one embodiment, a rotatable button overcap is included as a locking means to prevent inadvertent discharge.

摘要： A general anesthesia rebreathing system comprised of a disposable portion easily coupled to and decoupled from a permanent portion. The disposable portion includes conventional breathing tubing for coupling a source of fresh gas, as from an anesthesia machine, to a patient and in addition an overflow tube for coupling the patient end of the system to an overflow (popoff) valve, preferably mounted on the machine and constituting part of the permanent portion. The overflow tube entrance is located close to the patient end of the system and in communication with the tubing which conveys expired gas to a reservoir, such as a conventional breathing bag, mounted at the machine end. The arrangement assures that the patient''s initially expired dead space gas is conveyed by the tubing to the reservoir with subsequently expired alveolar gas being exhausted through the overflow tube and pop-off valve.

摘要： A central member connects two duplicate pressure regulator assemblies of the spring-urged diaphragm type, and this central member contains an orifice piece having a bore with a seat at each end of the bore. Separate valve heads each operated by one of the pressure regulator assemblies close against one of the seats, respectively. The central member has an inlet communicating with one of the seats and its respective valve head, and also has an outlet communicating with the other seat and its respective valve head. Pitot tubes establish communication between the outlet and pressure chambers on one side of each diaphragm. The regulator assembly operating the valve head on the downstream side of the orifice piece normally regulates gas pressure at the outlet, but, upon failure of that regulator assembly, the other regulator assembly automatically takes over control.

摘要： A safety air valve switch for a pressurized air line is provided. The valve may be in the form of an exterior sliding sleeve. The safety air valve switch for a pressurized air line moves between an open and a closed position. In the open position the safety air valve allows pressurized air to flow through an air line of, for example, a tire inflation hose. In the closed position the safety air valve switch prohibits the flow of air through the air line. The safety valve allows for safe venting of pressurized air when switching between the open and closed position.

摘要： An object of the present invention is to provide an emergency braking device for an automobile that is capable of preventing a safety-related accident by applying a braking force even when a brake pipe or the like is ruptured. To this end, the emergency braking device for an automobile of the present invention is an emergency braking device for an automobile that is added to an automobile that is braked by a pressure of main brake fluid transferred through a brake pipe when a brake pedal is stepped on and that is instantaneously and automatically switched to an emergency braking device when braking is not performed due to the rupture of the existing (main) brake pipe, or the like. The emergency braking device for an automobile includes a valve unit, an emergency pipe; a pressing part; and a pressure source.

摘要： The ventilation unit includes: an explosion-proof valve that permits gas to flow from the inside of a housing to the outside of the housing when internal pressure within the housing is higher than external pressure outside the housing by a value larger than or equal to a predetermined value, and is capable of returning to block the flow of the gas from the inside of the housing to the outside of the housing; and a ventilation membrane that permits gas to flow between the inside and the outside of the housing even when a pressure difference between the internal pressure and the external pressure is less than the predetermined value.
