Definitions

  • the present invention relates to a jack, in particular a micro-jack, comprising a substantially cylindrical hollow body in which is movably mounted a piston dividing the internal space of said body into two chambers of variable volume, each of which is provided with an orifice for the supply of pressurized fluid to this chamber or for its exhaust, and a device for supporting additional elements, if necessary, indicator of an operating parameter of the jack, such as bars, fixed on the external surface of the body.
  • the bars are fixed to the cylinder by screws in zones angularly offset for example by 90 °, supply or exhaust orifices, to allow free access to these orifices.
  • the object of the present invention is to overcome this drawback and to propose a jack of the type stated above, of small bulk.
  • the jack according to the invention is characterized in that the means for fixing the support device are mounted in the supply orifices.
  • the fixing means are formed by members capable of being each screwed into a supply orifice, each member being traversed by a channel allowing the passage of the pressurized fluid inside. cylinder.
  • this bar is of tubular shape and has an axial channel communicating at one end, at through a passage made in the fixing means, with a supply orifice while the other end serves as an inlet for supply fluid, the supply connections of the jack being able to be located at the same end of the jack.
  • the jack according to the invention comprises at least one control stitching device produced in the form of a flange supported by the support device advantageously in the form of a bar and having a passage channel aligned with a hole passing through the cylinder body.
  • Figures 1 to 3 show a micro-cylinder 1 according to the present invention, which is equipped with a device for support 2 adapted, in the example shown, to carry a magnetic sensor 3.
  • the jack comprises a substantially cylindrical hollow body 4 in which is mounted displaceable in a reciprocating movement a piston 5 which divides the interior of the jack in two chambers 6 and 7 of variable volume. Reference 11 designates the piston rod.
  • the cylinder is of the double-acting type.
  • Each chamber can be supplied with a pressurized fluid or exhausted through a supply orifice 8.
  • the body 4 comprises a tube 9 closed at each end by a tight closing flange 10.
  • the feed orifices 8 are formed in these flanges and extend perpendicular to the axis of these.
  • the piston 5 carries an annular permanent magnet 12 located between two sealing rings 13.
  • the magnetic sensor 3 is formed in the example represented by a relay of the Reed type, provided with a contact clearance 14 located inside of 'a bulb 15. Relays of this type are well known in the art and make it possible to signal, in a manner known per se, the passages of the piston 5 of the jack.
  • the support device 2 comprises two support bars 17 and two bar supports 18 each associated with a closure flange 10 of the jack.
  • the bars are advantageously formed by cylindrical rods, but can be of any other suitable shape. They are fixed to the supports 18 by fitting their ends into appropriate holes made in the parts forming the support-bar 18.
  • a very stable support device is obtained here for the magnetic sensors 3 or for any other desired accessory or additional device, intended where appropriate, to provide information relating to certain parameters of the operation of the jack. These devices will advantageously be supported by the rods 17.
  • the support device 2 is assembled to the jack 1 by fixing each piece of stop support 18 to a closing flange 10 of the jack, by means of a fixing screw 20 which is screws directly into the supply orifice 8 of this flange, provided for this purpose with a threaded portion 21.
  • each screw 20 comprises an axial supply channel 22 which la crosses entirely.
  • the head portion of the screw is shaped to allow connection to a supply tube or manifold (not shown).
  • the head has in Figure 2 a central threaded recess 23 having a diameter greater than that of the channel 22.
  • connection of the screw hollow to a supply tube 25 is obtained by the insertion of a push-in fitting 26 known per se.
  • Reference numerals 27 to 32 respectively designate an O-ring, a fan washer, a metal washer, a thrust element 30 and a retaining ring 31.
  • Figures 5 to 7 show another embodiment of the support device 2 and a cylinder 1 according to the present invention.
  • the support bars are tubular, which makes it possible to use at least one of these bars as a channel for supplying fluid under pressure to a chamber of the jack. In this way, it is possible to provide the two connections to the supply device, at the same end of the jack.
  • the bar support pieces and the fixing screws are somewhat special.
  • these elements are designated by references 18 'and 20'.
  • the bar holder 18 'on the right has the two supply ports indi quées par 32, 33.
  • These orifices or recesses shaped for connection to the supply system extend parallel to the axis of the jack.
  • the orifice 32 communicates directly with the fixing hole 35 of the support 18, intended for the reception of the fixing screw 20 '.
  • the orifice 33 communicates with the hole 35 for receiving the fixing screw of the other bar support 18 ′, by means of the corresponding tubular bar 17 ′ and the conduits 37, 38 formed respectively in the connection support 18 'and the support - bar on the left, that is to say without supply ports.
  • Figure 7 shows the fastening screws 20 'matched to the tubular bars.
  • the screws 18 ′ have, at the level of the conduit 38, a transverse channel 39 which communicates via an axial channel 40 with the internal space of the jack.
  • FIGS. 8 and 9 show an embodiment of a jack according to the present invention, in which the support device or more precisely the bars are used to support one or more control tapping flanges.
  • two tapping flanges 42 are interposed between the two bar supports 18.
  • Each flange has a channel 43 which passes through it.
  • the upper part of the channel is widened to form a threaded recess allowing connection to an external device.
  • These recesses could be made so as to allow an instantaneous connection of the type shown in FIG. 4.
  • the lower part of the channel passing through the flange communicates with the interior of the jack through a hole 45 passing through the tube 8 of the body of the jack.
  • control stitching devices can be used for any purpose.
  • the two flanges are arranged so as to allow the signaling of the end positions of the piston.
  • a logic device will be associated with each flange, for example with two inputs connected respectively to the corresponding supply orifice and to the flange.
  • the bars can be used as a support member for an additional device and / or to serve as a tube incorporated in the pressurized fluid supply system, of the jack, like this is illustrated in Figures 5 to 7.
  • the fixing screws can perform in addition to their actual fixing function, additional functions such as for example those of the speed adjustment means. To this end, it is necessary to ensure, as is known per se, that the cross section of passage of the pressurized fluid is variable.
  • the cylinders according to the invention which have been described and shown can be modified in various ways without leaving the scope of the invention.
  • the cylinders can be of the single acting type.
  • the control tapping flanges can be adjustable.
