FR2461229A1 - DRIVING DEVICE FOR CANON CYLINDER HEAD TRANSVERSALLY MOVABLE AT THE AXIS OF THE SOUL - Google Patents

Abstract

THE INVENTION RELATES TO A TRAINING DEVICE FOR A BARREL CYLINDER HEAD THAT CAN BE MOVED TRANSVERSALLY AT THE CORE AXIS. AT LEAST TWO HYDRAULIC CYLINDERS 4, 5 PLACED IN THE REAR BODY REGION 2 OF TUBE 1 COOPERATE WITH THEM, ONE 4 IS PARALLEL TO THE CORE AND DRIVEN BY THE RETURN TO BATTERY OR THE RETURN OF THE TUBE, THE OTHER 5 BEING PLACED AT A RIGHT ANGLE, IN THE DIRECTION OF MOVEMENT OF THE CYLINDER HEAD 3, WHICH IS CONNECTED TO THE CORRESPONDING PISTON ROD 7 SO AS TO BE ACTUATED BY THE EFFECT OF THE FIRST CYLINDER ON THE SECOND. THIS DEVICE, WITHOUT ADDITIONAL ENERGY ACCUMULATORS, HAS A SIMPLE STRUCTURE AND IS EFFECTIVE EVEN AT HIGH SPEED OF FIRE AND LOW RECOIL.

Description

The present invention relates to a device for

  flow for a gun breech displaceable transversely to the axis of the core and actuated according to the return to the battery

or the recoil of the tube.

  It usually takes a certain minimum distance of the tube to cause via levers or control cams

  the opening and / or closing movement of such cylinder heads.

  Shelling is also often imposed on

  recent model. The relatively small recoil that results is not always sufficient to exact the cylinder head. It has already been proposed cylinder maneuvering devices requiring only a relatively small decline and independent of the length thereof. The structure of these known devices having several parts telescopically fitted into each other is very complicated; they are also equipped

  additional energy accumulators consisting of

  spells and a little sdr operation, because the major efforts they undergo make them run high risks of repetition We also know a hydropneumatic cylinder head control

  In which the fixed part of the barrel comprises, instead of accumulating

  mechanical energy burners, springs, two hydraulic cylinders

  acting against a pneumatic accumulator of

  pressure. the movable pistons in the cylinders form pus-

  elastic evenings powered by a lever transmission from

  the cylinder head crank placed on the rear body of the tube.

  This device has the disadvantage of not being suitable for large

shooting speeds.

  The subject of the invention is a drive device for a gun breech displaceable transversely to the axis of the core and actuated as a function of the retraction into a battery or the recoil of the tube which, while being of simple structure and not requiring no additional energy accumulators, perfectly actuates the breech at high shooting speed, even in case of short stroke

back.

  This device is characterized in that it comprises at least two hydraulic cylinders mounted on the tube in the region of the rear body and associated in their operation, one

  two being parallel to the axis of the soul and actuable by the reaction

  in the battery or the rectal tube, the other being arranged per =

  perpendicular to the first, in the direction of movement of the cylinder head, connected to the piston rod of the second cylinder so that said cylinder head is actuated by the effect of the first

cylinder on the second.

  Such a construction offers the advantage of being little

  brante, inexpensive and applicable to almost all culas-

  its usual horizontal corner9 that open at the start of the school year

  in battery or recoil or for a fraction of these

  vements. We can limit the part of the displacement of the tube required

  appropriate sections, possibly different.

  In a preferred embodiment, the piston rod of the cylinder parallel to the axis of the core is drivable, on retraction battery or the recoil of the tube 9 because it hits a fixed stop so that the movement 9 of the tube continuing, the piston of the same cylinder moves internally to him and the

lindre.

  According to an advantageous extension for a cylinder head,

  when the battery is retracted, the device comprises on the cradle a latch in the locking position at rest and forming a stop for the piston rod of the first cylinder during the re-entry into

battery of the tube.

  In order to reduce the bulk, the second cylinder, parallel to the direction of movement of the cylinder head, can be placed in a recess of the rear body of the tube, and the first

possibly too.

  In a particularly rational arrangement, the cylinders exist in duplicate and are symmetrically distributed on both sides and above and below the tube. Organs

  may well have relatively small dimensions

  and their symmetrical arrangement avoids any inclination

  of the breech during his movement.

  This provides a space-saving arrangement in

  both on the tube, in order to actuate the cylinder head by hand, a manual pump acting on the cylinder or cylinders parallel to the axis

of soul.

  The invention will be better understood from the description

The reservoir can be reduced to small dimensions, because it is sufficient that it contains a quantity of liquid representing the volume displaced in the cylinders 4 less than that of the piston rods. The cylinders 4 and 5 are shown in the drawing only schematically and with dimensions with little identical, for which the required stroke of the tube substantially corresponds to the opening path of the cylinder head. We can still decrease

  this stroke of the tube giving a weaker section to the cy-

  lindres 5 acting directly on the cylinder head.
