A hydraulic adapter unit includes a hose connecting member and a pipe member. The hose connecting member is a substantially cylindrical hose connecting member, and includes: a hose fixing portion positioned at one end side of the hose connecting member and to which the hose is fixed; a first combining portion positioned at the other end side of the hose connecting member; and an intermediate portion linking the hose fixing portion and the first combining portion. The pipe member includes: a substantially tubular pipe body; a second combining portion disposed at the one end side of the pipe body and separably combined to the first combining portion of the hose connecting member; and a flange portion disposed at the other end side of the pipe body and formed so as to project outward in the radial direction of the pipe body and fixed to a hydraulic device.

A flange structure for connecting together two members each having a flow path with different angles which can control an increase in flow resistance and can realize easy and stable manufacture can include a first member and a second member connected to each other through a flange. A central axis of a flow path of the second member can be slanted at a first angle with respect to a central axis of a flow path of the first member. The flow path of the first member and the flow path of the second member are allowed to communicate with each other by an in-flange flow path formed in the flange, and a second angle constituted of an acute angle between a central axis of the in-flange flow path and the central axis of the flow path of the first member is smaller than the first angle.

Technology is provided for a fluid conduit assembly for connecting orthogonally oriented connections. The assembly includes a first tube arcuately extending from a first proximal end portion to a first distal end portion. The first proximal end portion includes a first fitting connectable to a first fluid connection. A second tube arcuately extends from a second proximal end portion to a second distal end portion. The second proximal end portion includes a second fitting connectable to a second fluid connection that is orthogonally oriented with respect to the first fluid connection. A coupling connects the first distal end portion and the second distal end portion. The first rigid tube is rotatably positionable with respect to the first fluid connection whereby a first distal axis and a second distal axis are substantially coaxially aligned when the first fitting and second fitting are connected to the first and second fluid connections, respectively.

In an implementation, a method of forming a hydraulic connection between a hydraulic component and a hydraulic hose includes threading a ferrule onto an end section of the hydraulic hose, crimping the ferrule to the hydraulic hose, and threading an annular gasket onto the hydraulic hose between the ferrule and an open end of the end section of the hydraulic hose. The method may include securing the hydraulic hose to a body of the hydraulic component by forming a seal between the body and the hydraulic hose by compression. Threading the ferrule onto the hydraulic hose may include threading an annular ferrule having a profile of a first truncated cone with a first half-aperture, and urging the ferrule towards an interface in the body of the hydraulic component, the interface having a profile of a second truncated cone with a second half-aperture different from the first half-aperture.

The invention pertains to a connecting element (1) for connecting a pipe end (2) to a component (3) of an air-conditioning system, wherein said connecting element comprises a base body (4) with a passage opening (5) for conveying through a refrigerant, a receptacle bore (6) for receiving the pipe end (2), wherein the receptacle bore (6) is arranged on a face side (7) of the base body (4) and corresponds to the passage bore (5), as well as a connection piece (8) that is arranged on the other face side (9) of the base body (4) and corresponds to the passage bore (5) on this side, wherein the connection piece (8) and the base body (4) consist of the same material and are realized in one piece, wherein at least one sealing element (12, 13) is arranged on the connection piece (8), and wherein the sealing element (12, 13) and the connection piece (8) are realized in one piece, as well as to a method for manufacturing such a connecting element.

A system for use with a fluid-containing body having a body wall with an opening and defining a body interior, and for use with a device to be inserted and extracted by said system via said opening into the fluid-containing body, said system having a central axis and comprising: a proximal portion configured for being attached to the body wall when mounting the system in said opening, and having a first chamber configured for receiving said device therein; a sealable interface having a first side facing said first chamber and a second side in a direction opposite said first chamber and defining a distal area configured for receiving said device from said first chamber; said sealable interface, when unsealed, being configured to allow passage therethrough of the device along said central axis between the first chamber and the distal area; a pressure regulating mechanism configured for regulating pressure within said first chamber between pressure at an upper exterior of the proximal portion and pressure at the distal area; and a second chamber encompassing at least a part of the distal area and configured for receiving the device therein; said sealable interface, when unsealed, being configured to allow passage therethrough of the device along said central axis between the first and the second chambers.

A sealing device for sealing a venting port of an extrusion apparatus. The sealing device includes a saddle having a saddle counter bore and a seal ring positioned in the saddle counter bore of the saddle. The sealing device also includes a barrel counter bore provided in a barrel of the extrusion apparatus. The saddle counter bore and the barrel counter bore are dimensioned to receive the seal ring, wherein when the seal ring is positioned in the saddle counter bore and the barrel counter bore, a seal is formed between the seal ring in all range of processing temperatures, the saddle and the barrel to prevent the unwanted leakage of high pressure melt.
