摘要： An elbow pipe joint includes a tubular first pipe connecting portion which allows another joint to be connected, a tubular second pipe connecting portion which has a second central axis intersecting a first central axis of the first pipe connecting portion, a hollow valve accommodating portion which is connected to the first pipe connecting portion and the second pipe connecting portion and which has a valve accommodating space communicating with a first inner hole of the first pipe connecting portion and a second inner hole of the second pipe connecting portion, and a flap valve device accommodated in the valve accommodating portion. The flap valve device is configured to pivot to switch between a valve open state where the first and second inner holes communicate with each other and a valve closed state where the first and second inner holes are blocked from each other.

摘要： An undersea hydraulic coupling member having a ring-shaped seal with multiple sealing surfaces extending radially inwardly therefrom is disclosed. The multiple sealing surfaces help guide the probe of the male coupling member into the female member without the risk of drag or galling of the receiving chamber or metal seal retained therein. The seal has an interfit with reverse inclined shoulders in the female member to restrain the seal from moving radially inwardly due to vacuum or low pressure. The seal also includes an internal biasing element to restrain the seal from moving radially inwardly during de-mating of the coupling members.

摘要： A hydraulic line coupling, for a hydraulic brake or clutch of handlebar-operated vehicles, having a line connection piece with a hydraulic line extension and a housing with a coupling opening, in which the line connection piece for coupling the line to the housing can be disposed. The connection piece comprises a passage connected to the line. A valve device is disposed in the housing and is configured such that the valve device closes the connection for the connection piece when the connection piece is not in the coupling opening. The line coupling has a seal, with which seal the valve device closes the connection for the connection piece when the connection piece is not in the coupling opening. With the seal, the connection piece seals the passage from the environment when the connection piece is in the coupling opening.

摘要： A rapid-connect gas coupler is shown and described herein. In an embodiment, the rapid-connect gas coupler includes a spring-loaded probe within a probe cavity, which is defined by a housing and one or more latch segment. The probe can engage with a gas connector, which causes the latch segment to engage and couple with the gas connector.

摘要： A connector assembly has a main body, a valve, a spring, a quick connecting device, and a seal. The valve is moveably mounted in the main body and has an adaptor, a valve body, and a sealing assembly. The valve body is spaced from the adaptor and has a closed end away from the adaptor, an open end, and multiple through holes radially defined in the valve body. The seal is clamped between the valve body and the adaptor to connect the valve body with the adaptor and has a tubular sleeve and a clamped flange. The tubular sleeve has an end. The clamped flange is radially formed around and protrudes from the end of the sleeve and clamped between the open end of the valve body and the adaptor.

摘要： A quick coupling engageable under pressure comprises a first longitudinal body longitudinally having an internal cavity open at the ends along which it is supported slidably in contrast to and by action of elastic means, a second longitudinal body longitudinally having an internal cavity open at the ends and equipped with an opening and closing valve to the flow of a fluid under pressure, the first body and the second body having locking means adapted to cooperate for locking the coupling in the engaged position, the coupling in use, in the disengaged position in which it is supplied with a fluid under pressure acting in closure on the valve, having surfaces wet by the fluid under pressure configured and arranged to eliminate the volume variation of fluid under pressure present within the coupling as the position assumed by the second body in the first body varies.

摘要： This invention relates to a fitment assembly used for dispensing liquids from flexible bags. The connector engages a valved fitment for a container for holding and dispensing fluid. The fitment includes a spout connected to the container and a sliding internal valve body and an external valve body securely positioned within the spout. The connector has a fitment end mateable with the fitment so as to compress the top edge of the external valve body so as to form a seal between the external valve body and the dispensing connector. The external valve body through circumferentially placed apertures allows for substantially complete drainage of the flexible bag.

摘要： A quick connect assembly having a female fitting attached to an end of a first fluid coupling and exhibiting an interior passage defined by a plurality of linearly extending and circumferentially spaced fingers. Undersides of said fingers collectively define a concentric concave profile an inwardly recessed distance from a connecting end. A male fitting attaches to an end of a second fluid coupling and includes an annular projection at an intermediate location generally matching the concave profile. Upon inserting the male fitting, the female fingers outwardly deflect, following which they inwardly retract concurrent with the projection seating within the interior concave profile. A covering cap is supported upon the male fitting and, upon displacing over projecting ends of the fingers, prevents inadvertent disengagement of the fittings.

摘要翻译： 一种快速连接组件，其具有连接到第一流体联接器的端部并具有由多个线性延伸且周向间隔开的指状物限定的内部通道的阴配件。 所述指状物的下侧共同地限定了与连接端部向内凹陷距离的同心凹形轮廓。 阳配件附接到第二流体联接器的端部，并且在通常与凹形轮廓匹配的中间位置处包括环形突起。 在插入阳配件时，雌指向外偏转，随后它们与内凹凹形轮廓内的突出座同时向内收缩。 覆盖帽支撑在阳配件上，并且在指状物的突出端上移位时，防止配件的意外脱离。
