摘要： A rotary valve assembly is disclosed in which a rotary valve member is located within a casing having one or more fluid inlets and a plurality of fluid outlets. The rotary valve member has a fluid conduit which extends in a generally radial direction and which communicates with the fluid inlet. Fluid orifices communicate with the fluid conduit and exit through opposite sides of the rotary valve member to thereby minimize, or eliminate altogether, axial forces acting on the rotary valve member. Fluid outlet passages communicate with the two fluid orifices during at least part of the rotation of the rotary valve member to direct the pressurized fluid to the valve outlets. The rotary valve may include a pair of rotary valve members drivingly connected to each other such that they rotate synchronously. The connection may include gear teeth formed on the adjacent peripheries of the rotary valve members such that rotation of one of the valve members causes rotation of the other. Each valve member may have a separate fluid inlet and separate fluid outlets.

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： This injector with two valves (7, 10) which open at different fuel pressures so as to establish a primary flow regime and then a secondary flow regime is characterized in that the primary regime is enriched with fuel via an orifice (21) which adds a branch to the primary flow path of the fuel, but which is closed when the secondary valve is displaced so as to prevent enrichment of the fuel in the secondary regime. This invention applies in particular to certain aircraft engines.
