An intake pipe includes a plurality of passages that join in a section upstream of the throttle body. The intake pipe includes an interference prevention member that prevents air passing through a specific one of the passages from flowing into the other passages. The interference prevention member is a thin plate and is formed in a confluence portion of an adjacent pair of the passages.

An elevator for lifting pipe having an exposed bottom edge or an internal groove. A channel member has one end hingedly connected to a rod adjacent a first end of the rod and has a second end connected to a sector-shaped plate. A tubular member is slidably positioned on the rod and is connected to the sector plate with a linkage which allows the sector plate to move from a collapsed position to a splayed-out position as the tubular member is moved toward or away from the sector plate. The sector...

The invention relates to a pipe coupling comprising a socket component and an insert component which is partially insertable to securely fit into the socket component. A ring groove between the socket component and the insert component is sealed by a ring seal. The socket component is releasably connected to the insert component by means of a union nut which contacts a shoulder of the insert component rearwardly for joined movement into the closed position. The union nut is screwed onto the sock...

A filler device or pipe comprising: a filler neck including a pouring inlet, a neck connection portion, and a connection pipe which includes a bellows part and which is connected to the neck connection portion. Fuel is injected through the pouring inlet and fed into the fuel tank through a filling passage of the filler device. The filler device further includes an inner tube including a tube body formed of a flexible elastomer material, which is inserted into the connection pipe. The tube body a...

A tool is provided for notching an end of a pipe. A punch is provided with a first cutting edge opposite a second cutting edge. The punch is coupled to a punch holder which is configured to move vertically relative to a collar supported upon a base. A pipe support provides a preferred form of die to hold the pipe adjacent the punch. The pipe support includes a first edge, second edge, third edge and fourth edge which can be selectively presented for supporting the end of the pipe adjacent the pu...

A heat pipe assembly (10/110), under vacuum and having a working substance charged therein, comprising generally an evaporator (12/112) adapted to evaporate the working fluid and a condenser (16/116). The heat exchanging condenser is in fluid flow communication with the evaporator. The condenser is adapted to condense evaporated working substance received from the evaporator and has a reservoir (30/130), located at a higher elevation than the evaporator, for collecting liquid working fluid there...

To seal a pipe mortar, a sealing element (3, 6) is inserted between the pipe (1) and the base (2), with the element elastically balancing out the axial relative movements between the pipe (1) and the base (2). The sealing element (3) is preferably prestressed, with the gas pressure supporting the sealing effect. The sealing element (3, 6) can be a U-shaped or L-shaped steel ring. In the U-shaped sealing element (3), the legs (3.1) are axially prestressed to the extent that the sealing ring (3) a...

A clad pipe includes an external layer and a coating layer made of Ni base anticorrosion alloy. Both end portion areas of the coating layer are formed by a build-up welded layer (Ni base alloy of composition 1) on the inner surface of the external layer. Other areas are formed by a Ni base alloy layer (Ni base alloy of composition 2) fusion-bonded to the build-up welded layers and the inner surface of the pipe, a solidus-curve temperature of the Ni base alloy layer being 1300.degree. C. or below...

Pipe brackets and a pipe hanging system are provided for supporting fluid-carrying ducts or pipes along a wall or suspended from a ceiling of a building structure. The pipe hanging system can position and support a pipe or system of pipes in any position and to provide a constant centerline path of each pipe segment irrespective of changes in the diameter of the pipe.

A pipe coupling is disclosed which comprises a plug (14) and a socket (12). When the plug is inserted into the socket, the plug first urges sleeve actuators (28) radially outward to axially move a sleeve (22) and, thereafter, urges locking elements (20) radially outward to move the sleeve further. Eventually, the locking elements and sleeve actuators are fitted within a locking recess (14-2) of the plug to securely connect the plug and the socket.
