摘要： A venting and aerating arrangement for closed flow systems for water of fluctuating temperature is disclosed. A vent casing, defining an air collecting chamber, extends upwardly from a horizontal conduit of the system. A float controlled vent valve is arranged in the upper portion of the casing. A grid of spaced rods is arranged in the junction between casing and conduit and extends into the flow passage of the conduit to break up bubbles of air and other gases with the liberated gas ascending into the air collecting chamber. An improved valve construction is also disclosed. The valve has an exteriorly threaded valve body with an axially extending flow passage. A first axial extension on the valve body has a smaller diameter than the valve body proper. The valve body has a plane end surface forming a valve seat surrounding the flow passage. An exteriorly threaded cylindrical closure body of the same diameter as the valve body and having a second axial extension of smaller diameter is included in the valve. A spring engages the threads of the valve body and closure body to urge the end surface of the closure body against the valve seat. The closure body is adjustable relative to the valve body for adjusting spring tension and valve operational limits.

摘要： Vent valve assembly for hot water boiler of type used in aircraft galleys permits trapped air in the boiler to escape during the initial fill. The valve includes a floating ball which rises as the boiler is filled so as to seat against an o-ring for sealing the boiler under pressure. A flow diverting plate positioned under the ball permits escaping air to rise rapidly around the ball without causing the ball to lift and be prematurely sealed against the o-ring. The plate also prevents the ball from blocking the air which must enter the boiler when it is drained.

摘要： A vent system includes a spring-loaded closed vent valve mounted in the upper portion of the truck tank and a spring-loaded closed safety valve mounted in the bottom of the tank. The safety valve has a discharge portion carrying an actuator pin which disengagably abuts the underside of the safety valve member and is actuated to lift the valve member to permit flow of gasoline from or into the tank. The vent valve member is operatively connected to the safety valve member by an actuating rod so that the vent valve is opened or closed when the safety valve is opened or closed. The safety valve, actuating rod and vent valve are provided with an overboard vent passage which extends from an inlet in the safety valve member to an outlet in the vent valve member. When the actuator pin is actuated to open the safety valve, the inner end of the pin covers the vent passage inlet and vapors are vented from the tank through the vent valve in a normal manner. When the safety valve is closed, a small spring carried on the actuator pin urges the inner end of the actuator pin away from the safety valve member, thereby opening the vent passage so that the discharge portion of the safety valve is vented overboard. This eliminates the vacuum effect normally created in a discharge conduit connected to the safety valve, permitting it to be gravity drained after the safety valve has been closed.

摘要翻译： 排气系统包括安装在卡车罐的上部中的弹簧加载的关闭排气阀和安装在罐底部的弹簧加载的关闭安全阀。 该安全阀具有一个排放部分，该排放部分承载着可分离地邻接安全阀构件下侧的致动销，并被致动以提升阀构件以允许汽油从罐中流出。 排气阀构件通过致动杆可操作地连接到安全阀构件，使得当安全阀打开或关闭时，排气阀打开或关闭。 安全阀，致动杆和排气阀设置有从安全阀构件的入口延伸到排气阀构件的出口的舷外通气通道。 当致动器销被致动以打开安全阀时，销的内端覆盖通气通道入口，并且蒸汽通过通气阀以正常方式从罐排出。 当安全阀关闭时，执行器销上承载的小弹簧将促动器销的内端推向远离安全阀构件，从而打开排气通道，使得安全阀的排放部分被排出。 这消除了在连接到安全阀的排放管道中通常产生的真空效应，允许其在安全阀关闭之后被重力排出。

摘要： A valve member for an air eliminator is a flexible band or reed secured at one end to a movable float and at the other end to the housing adjacent a valve seat surrounding a port therein. A flexible sealing band formed of a resilient material overlies and is coextensive with the flexible band to provide a hermetic seal around the valve port when the float moves into a valve closing position. The sealing band is apertured where it overlies the port to equalize the pressure across the sealing band when it is positioned over the port.

摘要： An evaporation control device consists of two spherical balls which float in a housing defining a cavity so that the balls move up and down in accordance with the fuel level in the tank to allow the top ball to engage a conical seat to seal the vented passageway from the fuel tank to the engine. The spherical contact surfaces between the two balls allow quick and easy movement of the top ball to seal the opening at once where gasoline moves toward the opening.

摘要： A hydraulic powered brake and parking brake arrangement powered by the power steering gear pump, and a pressure control assembly in the system. The control assembly acts as a pressure regulator for the parking brake actuators, provides for pressure relief to prevent a build up of excess pressure to the parking brake regulators, assures the provision of brake hold off pressure to the regulators even though the pressure from the power steering pump falls below the pressure required by the actuators, and provides for limiting the pressure available to the assembly when the power steering gear pump is working against a pressure in its upper range of capability.
