    摘要: A multi-stage pilot valve is disclosed for selectively supplying a working fluid to and venting from a reaction jet main stage actuation chamber. In a preferred embodiment of the invention, the pilot valve comprises a solenoid actuated ball and socket flapper valve having a pressure inlet, an exhaust outlet and a service port. The first stage service port is in fluid communication with a second stage actuation chamber. A piston disposed in the second stage actuation chamber operatively engages a ball member of a ball-and-seat type valve comprising the second stage valve. The second stage valve also comprises a pressure inlet, an exhaust outlet and a service port. The piston and ball are sized relative to each other such that when the second stage actuation chamber is pressurized by the first stage, the force is sufficient to seat the ball against the second stage pressure inlet. This shuts off the flow of high pressure gases to the second stage service port and permits the second stage service port to vent through the exhaust port. When the second stage actuation chamber is vented by the first stage valve, the pressure acting on the ball is sufficient to seat the ball against the second stage exhaust outlet. This opens the second stage pressure inlet to permit high pressure gases to enter the second stage service port. The bi-directional movement of the ball member of the second stage valve is accomplished entirely by fluid pressure, thus enabling a fast responding, high flow rate regulation of the hot gases using low electrical power and eliminating the use of springs or other resilient members that would be of dubious reliability operating in a hot gas environment.

    摘要: The invention relates to the field of power machine building and may be used in mixing devices of gas generators for driving gas turbines, in particular, for liquid-propellant rocket engines. A gas generator comprises a cover with a hole, a bottom with a mixing chamber, a housing with an axial duct communicating with the hole in the cover. The housing is fastened in the cover hole and/or in the mixing chamber of the bottom. Grooves are made uniformly along the circumference of the cross section of the housing in the bottom and/or on the housing. The hole in the cover and the axial duct are designed to supply propellant, and the space between the cover and the bottom and the grooves in the bottom and/or on the housing are designed to supply an oxidizer. A propellant space is made in the cover, and the axial duct communicates through the propellant space with the hole in the cover by means of tangential propellant supply holes. An annular oxidizer duct and a cylindrical mixing chamber are additionally made in the module housing. The annular oxidizer duct is placed concentrically to the axial duct and communicates coaxially with the cylindrical mixing chamber, and by tangential oxidizer supply holes communicates with the space between the cover and the bottom.
