A fluid circuit, in particular for an aircraft, comprising at least one first duct (1) and a first connecting member (5), at least one second duct (2) and a second connecting member (6), a connector piece (3), for joining the two connection ends of the ducts (1, 2) in a leaktight manner, comprising a central sleeve (4) configured to cooperate, at a first end, with the first connecting member (5) and, at a second end, with the second connecting member (6), the central sleeve (4) having a plurality of flexible teeth (41) in order to correct any error in alignment between the first axis (X1) and the second axis (X2).

A magnetic filter (10) includes first and second separation chambers (10, 12). The separation chambers (10, 12) each have an inlet and an outlet, and the separation chambers (10, 12) are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement (28) connects both inlets to a single inlet pipe, and an outlet port arrangement (30) connects both outlets to a single outlet pipe.

A slip joint assembly for joining multiple pipes is provided. The slip joint assembly includes a flow expander that is connected to a downstream pipe and is tapered toward a forward end. An inlet bellmouth is coupled to the forward end of the flow expander and defines a flared inlet positioned within an upstream pipe. An annular seal assembly is coupled to the upstream pipe and includes a ball seal positioned around and forming a seal with the flow expander to operably couple the upstream pipe and the downstream pipe. An internal diameter of the annular seal assembly is smaller than a diameter of the flared inlet.

A first projection is formed on the outer periphery of a bulb part, a second projection is formed on the socket rear end of the bulb part, a tapered part is formed with a decreasing diameter from the inner periphery of a heel part to the inner periphery of the second projection, and a third projection is formed on the tapered part. A first dimension B from the first projection to the third projection in an inclination direction opposite to an inclination direction G of the tapered part is smaller than a second dimension C from the first projection to the second projection in a radial direction A.

A liquid medium delivery device has: first and second rigid pipes configured to receive flowing liquid medium from a pump. The first rigid pipe has a first curved portion. The second rigid pipe has a second curved portion. The curved portions are at least partially nested. An actuator is connected to the first rigid pipe or the second rigid pipe or both the first and second rigid pipes. The actuator is operable to move either the first rigid pipe or the second rigid pipe so that either the first curved portion or the second curved portion moves along a common arc of both the first curved portion and the second curved portion. The liquid medium delivery device has an outlet through which liquid medium, for example liquid manure, can be pumped.

A first projection is formed on the outer periphery of a bulb part, a second projection is formed on the socket rear end of the bulb part, a tapered part is formed with a decreasing diameter from the inner periphery of a heel part to the inner periphery of the second projection, and a third projection is formed on the tapered part. A first dimension B from the first projection to the third projection in an inclination direction opposite to an inclination direction G of the tapered part is smaller than a second dimension C from the first projection to the second projection in a radial direction A.

An adjustable pipe and methods for manufacturing and installing the same may include at least two pipes, a seal structure and a base coupling. The adjustable pipe may be for fluid connection between a first object and a second object. The at least two pipes may include a first pipe and a second pipe that is configured to be received by at least a portion of the first pipe. The adjustable pipe may also include a first inner collar proximate the first end of the first pipe and a second outer collar proximate the second end of the second pipe. The seal structure may be provided between the first pipe and the second pipe and between the first end of the first pipe and the second outer collar proximate the second end of the second pipe.

A sealing device for an exhaust manifold in a vehicle having longitudinally overlapping first and second components separated by a gap includes a plurality of backing rings for positioning in the gap between the first and second components. An intumescent mat is positioned between and abuts the backing rings. A retainer connected to the first and second components covers the gap to prevent the backing rings and mat from exiting the gap while allowing for relative longitudinal and rotational movement between the first and second components.

A system is disclosed for measuring displacement of a regulation system for a variable pitch axial fan. The system includes a hub having a plurality of adjustable pitch fan blades. A hydraulic cylinder is connected to the hub. A piston is disposed within the hydraulic cylinder. The piston is coupled to a piston shaft that is axially movable with respect to the hub. The piston shaft is coupled to an actuation assembly for adjusting the pitch of the plurality of adjustable pitch fan blades in response to an axial movement of the piston. A rotating oil union includes a housing and an interior element, the interior element coupled to the hydraulic cylinder so that rotation of the cylinder and the hub causes rotation of the interior element. The rotating oil union includes a static housing and a central probe fixed to the static housing. The central probe extends through respective openings in the interior element, the hydraulic cylinder, and the piston. The central probe is configured to sense an axial position of the piston and to generate a signal representative of said axial position. A method for using the system is also disclosed.

A threaded retainer including a body having a through-bore therein, a first screw thread operatively arranged on an outer surface of the body, wherein, the first screw thread is arranged to secure the threaded retainer to a fluid connector having a second screw thread, the first screw thread corresponding with the second screw thread, a first shoulder arranged on the body, wherein the first shoulder is arranged to abut against a second shoulder of the fluid connector, and an axial gap between the fluid connector and the threaded retainer, wherein the axial gap is formed when the fluid connector is secured to the threaded retainer.
