Definitions

  • the present invention relates to so-called electro-valves intended to control either the resetting into firing position or the firing of an automatic fire-arm.
  • the object of the present invention is to provide an improved fire-arm control electro-valve which is better adapted to meet the requirements of practice than those used for the same purpose up to the present time, and more especially an electro-valve capable of controlling at will either the resetting into firing position or the firing of the fire-arm through a simple operation and by means of a single electro-magnet.
  • I provide an electro-magnet, including a stationary armature and a movable core, or inversely, so as to be capable of acting in two opposed directions, the movable part being displaced in one direction or the other according as the current that flows through at least one of the parts of the electro-magnet is itself sent in one direction or the other.
  • the essential feature of my invention consists in providing an electro-valve intended to perform the two above mentioned operations with a single electro-magnet adapted to act either in one direction or in the opposite one.
  • the only figure is a diagrammatic sectional view of an embodiment of the fire control device according to the invention.
  • I have shown at I a case or chamber fed with compressed air or any other fluid under pressure through a conduit 2.
  • This case I is provided with two valves 3 and 4, including respective balls 3a and 4a adapted to cooperate with two seats provided in the case in question. These valves control the communication between the inside of this case I and two chambers 5 and 8, respectively, connected with conduits 2I and 22.
  • the device adapted to be operated by compressed air or another fluid under pressure which produces the resetting of the fire-arm into firing position is fed with compressed air or fluid under pressure through conduit 2
  • Valves 3. and 4 are respectively operated by push-pieces I and 8.
  • the armature 9 is stationary and it is energized by an electric current fed to terminals H and I2.
  • the core is for instance constituted by a permanent magnet.
  • this core must be of disymmetrical structure, being for instance divided into two portions Ill and Ilia by a partition, diagrammatically illustrated by a solid black line in the drawing.
  • the direction of the current fed to terminals I I and i2 of the e1ectro-magnet armature is controlled, for instance, by a reversing switch such as 2%.
  • the displacements of the electro-magnet core in one direction or the other are transmitted, through push-pieces I3a and I ia, to levers I3 and I4, respectively, pivoted, at I5 and IE, to the frame which comprises the valve casing I-
  • levers I3 and I4 respectively, pivoted, at I5 and IE, to the frame which comprises the valve casing I-
  • push-pieces l and 8 which control valves 3 and 4, respectively.
  • Two return springs I1 and I8, interposed between the ends of the electro-magnet core, and fixed abutments, respectively designated by reference characters IS and 28, are adapted to bring back the core into its intermediate neutral position after it has performed one operation in one direction or the other.
  • levers I3 and I4 which cooperate with push-pieces I3a and I la are fork-shaped and engage corresponding transverse pins carried by said push-pieces.
  • Valve 3 controls, for instance, the resetting of the fire-arm into firing position, the fluid under pressure from conduit being fed to conduit 2
  • valve 4 controls the firing of the fire-arm, the fluid from conduit 2 being sent into conduit 22 by the opening of said valve 4.
  • Such a device is in itself capable of working in a fully satisfactory manner.
  • it is important to ensure a very sudden operation of the device to be controlled, which of course necessitates a very quick opening of the valves.
  • I provide, between each end of the core of the electro-magnet supposed to be in its neutral position and the end of the corresponding push-piece l3a or I 4a, a certain play E, whereby the core of the electro-magnet is given the possibility of gathering speed before striking said push-piece, and thus ensures the quick and accurate opening of the corresponding valve 3 or 4.
  • levers such as I3 and M
  • the shape and arrangement of the levers shown have no limitative character.
  • levers may be dispensed with, the movable part of the electro-magnet then acting directly on the valves. Any suitable transmission may be used for performing the function of these levers.
  • electro-magnet may be of any type whatever, within the scope of the invention, and the part thereof that is stationary is not necessarily the armature as shown.
  • a control system for operating either of said two devices which comprises, in combination, a source of fluid under pressure, means for controlling the communication between said source of fluid under pressure and said devices respectively, an electromagnet including two parts movable with respect to each other, means for transmitting the relative displacements of said parts to said communication controlling means such that a displacement in one direction corresponds to the operation of one of said devices while displacement in the opposite direction corresponds to the operation of the other device, means for feeding energizing electric current to said electro-magnet, and means for reversing at will the direction of said current.
