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 fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.

摘要： This document describes devices and methods for reducing liquid spillage, such as fluid coupling devices that include one or more apertures that reduce spillage when the fluid coupling devices are disconnected. In some embodiments, the one or more apertures are designed with features to increase a level of acceleration that liquid within an internal volume of the fluid coupling devices would need to be exposed to in order to spill from the internal volume via the one or more apertures.

摘要： Male or female fluid coupling element and fluid coupling including such an element This coupling element has a body and a nozzle. The body delimits a housing for partially receiving the nozzle. The nozzle has a tubular part and a flange received in the housing. Two sealing barriers formed by at least one sealing joint are interposed between a rear surface of the flange and a front face of the body, between a front surface of the flange and a rear face of the body, respectively. A plug caps an inner conduit. Portions of the inner conduit communicate through at least one passage opening into an inner volume of the nozzle, forward of the plug, and on an outer peripheral surface of the flange. An inner chamber is separated from the inner conduit by the body, the flange, the plug and the first sealing barrier.

摘要： The invention is directed to a device for inflating a tire that includes a housing with at least one first connection port and at least one second connection port. The second connection port includes connecting means to interconnect the device with a pressure tank. The first connection port is fluidically connected to the second connection port by means of a fluid passage. Furthermore the device comprises a first valve. When a pressure tank is connected to the second connection port and when the first valve is in a closed state, the first valve is suited to prevent air from flowing from inside of the pressure tank out of the first connection port. When the first valve is in an open state, it is suited to allow passage of air from inside of the pressure tank through the fluid passage to the first connection port. The device further includes a second valve that is connectable to an inflator for pressurizing the tank.
