Definitions

  • Our invention relates to controls for internal combustion engines and more particularly to an automatic manifold pressure regulator for supercharged aircraft engines such as are used in target drones and the like.
  • An object of the present invention is to facilitate engine control by providing a simplified device for controlling throttle position.
  • Another object of the invention is to adapt engines to pilotless aircraft by providing a means for maintaining manifold pressure substantially constant.
  • a further object of the invention is to obtain automatic control of engine operation by providing a means of automatically varying throttle position to obtain substantially uniform manifold pressure during variable oper ating conditions.
  • FIG. 1 is a diagrammatic view of an air induction system used in a supercharged internal combustion engine.
  • FIG. 2 is a longitudinal cross-sectional View of the air throttle control shown in FIG. 1.
  • FIG. 1 a portion of a preferred air induction system for an internal combustion engine is illustrated as comprising an air intake 10, a throttle valve 11, a supercharger 12, a supercharged air manifold induction means 13, having the throttle valve 11 therein, such that manifold pressure at all times exceeds atmospheric pressure in the manifold 13.
  • a throttle valve control device 14 having an actuating piston rod 15, is mounted in any suitable fashion so that the piston rod 15 may operate the throttle valve by some means such as through a bellcrank 16 pivoted at 16A, a link 17, and a lever 18 connected to the throttle valve 11 which is pivoted at 11A. Extension of the piston rod 15 acts to open the throttle valve 17, while retraction acts to close it.
  • the control device 14 preferably comprises a cylindrical two-part housing 20 having a mounting bracket 21 secured thereto, and an inner wall 22 secured intermediate the ends 23 and 24, dividing the interior into a manifold pressure chamber 25 and a control chamber 26 which is further divided by means of a piston 27 into a regulating pressure compartment 26A and an atmospheric pressure compartment 26B.
  • the chamber 25 is openly connected, by any means such as a conduit 28 to the manifold 13 downstream of the throttle valve 11, transmitting manifold pressure into the chamber 25 and through a variable metering valve 29 into the regulating pressure compartment 26A.
  • the compartment 26B is openly connected, through a port 30 or the like, to the atmosphere.
  • valve 29 will normally be open to some degree, when it does close, the pressure in compartment 26A may leak out through passages 31 and 32 provided in the piston rod 15.
  • valve 29 is made variable with respect to variations of manifold pressure.
  • a sealed spring loaded bellows 35 is provided in the chamber 25, one end being mounted on a stud 36 carried by the housing end wall 24 and threaded to provide axial adjustment of the bellows 35.
  • the valve 29 is cylindrical metering pin as shown, having an axial passage 37 openly connected by a transverse passage 38 with the chamber 25 and by a second transverse passage 39 with an annular groove 40, the valve 29 fitting through a bore 41 in the wall 22.
  • the end of the valve 29 has a tapered end 42.
  • the bellows 35 collapses and expands to move the valve 29 axially in the bore 41, variably admitting manifold pressure to the compartment 26A past the end 42.
  • This position of balance may be adjusted by turning the threaded stud 36 to vary the neutral position of the valve 29, which will provide calibration of the control device 14 to any desired manifold pressure consistent with optimum engine performance.
  • a manifold pressure regulator for supercharged internal combustion engines comprising air manifold induction means having a throttle valve therein, a supercharger upstream of said throttle valve, and a throttle valve control mechanism having a manifold pressure chamber openly connected to said air induction means downstream of said throttle valve, a first sealed bellows in said manifold pressure chamber, a second chamber having a pressure responsive element therein separating said second chamber into a first and a second compartment, a valve axially slidably carried intermediate said manifold pressure chamber and said first compartment and operatively connected with said bellows to open communication between said manifold pressure chamber and said first compartment when the manifold pressure sensed by said bellows is below a predetermined absolute value and to close communication between said manifold pressure chamber and said first compartment when the manifold pressure sensed by said bellows is above said predetermined absolute value, the second compartment being openly connected with atmosphere, said pressure responsive element being operatively connected with said throttle valve and adopting a position of balance determined by the differential between
  • a manifold pressure regulator for internal combustion engines comprising air manifold induction means having a throttle valve therein, a supercharger upstream of said throttle valve and a throttle valve control mechanism comprising a housing having a first and a second chamber separated by a fixed wall, a valve means axially slidably carried in said wall selectively openly connecting said chambers, means openly connecting the first chamber with said manifold induction means downstream of said throttle valve, a sealed bellows carried in the first chamber and operatively connected with said valve means to variably open communication between said first chamber and said second chamber when manifold pressure as sensed by said bellows varies below a predetermined absolute value and to close communication between said chambers When manifold pressure increases to said predetermined absolute value, a second pressure responsive means in said second chamber and operatively connected with said throttle valve to actuate same as metered manifold pressure in said chamber varies.
  • said second pressure responsive means comprises a piston axially slidable in the second chamber, the end of said second chamber axially opposite from said wall being openly connected with atmospheric pressure, said piston arranged to seek a position of balance determined by pressure differential between metered manifold pressure and atmospheric pressure, said piston being connected to said throttle valve to actuate same as the differential between metered manifold pressure and atmospheric pressure varies.
  • manifold pressure regulator as defined in claim 4 and including means axially adjusting the position of said bellows with respect to said passage whereby the absolute value of manifold pressure which will produce a closing of communication between said chambers may be selectively Varied.
