摘要： A ball-type sealing device is disclosed for preventing fluid flow out of an orifice wherein the sealing ball is mounted in a body member so as to have both radial or transverse and axial degrees of freedom. The sealing ball, which has a diameter greater than that of the orifice, is mounted in a chamber defined by the body member such that a portion of the ball extends through an aperture in the end of the chamber to the exterior of the body member. The sealing ball is positioned by a pushrod slidably extending into an elongated hole defined by the body member such that one end of the pushrod, having a first contact surface S.sub.1, is in contact with the sealing ball. The opposite end of the pushrod is associated with a second contact surface S.sub.2 which has an area smaller than the contact surface S.sub.1. The sealing ball may be accurately placed in the orifice to be sealed since it has both a transverse degree of freedom, due to the diameter of the chamber in the body member being larger than the diameter of the sealing ball, as well as an axial degree of freedom. Pressure exerted on the sealing ball along the longitudinal axis of the body member exerts a force on the pushrod which, in turn, causes permanent axial deformation of a crush portion of the body member adjacent to the second end of the pushrod. This deformation provides the necessary axial play or clearance between the pushor and the ball.

摘要： A fluid metering device including a metering valve capable of sliding in a bushing under fluid feed pressure in order to enable a fluid to be admitted and then ejected. The valve can have, at a first end, an opening opening out into a longitudinal fluid admission bore, and at a second end forming an end wall, a valve head provided with fluid metering slots opening out into the longitudinal bore and defining varying flow sections. The valve head can further include at least one substantially transverse orifice disposed downstream from the metering slots in the fluid flow direction, the orifice communicating with the longitudinal bore and defining at least one fixed flow section.

摘要： A fuel injector is disclosed for injecting fuel into a combustion chamber a gas turbine engine which includes an injector nozzle having a central axis, first and second fuel injection paths in which one of the fuel injection paths supplies fuel to the injector nozzle while the other fuel injection path has an outlet displaced from the axis of the injection nozzle, a single fuel supply conduit which supplies fuel to both of the fuel injection paths, and a metering device which controls the flow of fuel from the single fuel supply conduit to the first and second fuel injection paths. The metering device may be a fuel metering valve assembly which has a piston defining a fuel metering orifice biased against a valve seat around an opening which communicates with the single fuel supply conduit. The piston is biased into engagement with the valve seat by a resilient bellows attached between the piston and a fixed structure.

摘要： A valve is disclosed having a valve piston slidably movable within a valve casing. The valve also includes a spring biasing the valve piston against a valve seat such that the valve is normally closed, but may be opened when the pressure acting on the valve piston exceeds the biasing force of the spring. In order to assure perfect sealing between the valve piston and the valve seat, the valve seat is formed on a member which is movably mounted in the valve casing by a generally annular elastic element. The elastic element connects the valve seat to the valve casing, as well as a shoulder extending from the valve casing into the valve chamber,d such that an axial clearance exist between the valve seat member and the shoulder, and a radial clearance exists between the valve seat member and the valve casing under all operating conditions of the valve. Such clearances enable the valve seat member to move axially and radially so as to assure perfect sealing between the valve seat and the valve piston.

摘要： A fuel valve for a fuel flow injection circuit, operating on electrical energy rather than hydraulic energy. The fuel valve has a valve body, a first fuel inlet opening, and a distribution assembly having a plug rotating in a bushing, the plug and bushing each having an opening slit. The valve body includes a fuel outlet opening section made by an overlapping area between the opening in the bushing and the opening in the plug. A plug position unit is provided to control a position of the plug in rotation, and the plug position unit is disposed in the valve body. The valve body further contains an electric motor that drives a rotation of a reduction gear assembly, the reduction gear assembly comprising an input shaft and an output pinion. The plug comprises a toothed sector engaging on the splines of the reduction gear assembly output pinion such that rotating the electric motor causes a rotation of the plug.
