  • the source 34 is typically constituted by a compressor, in particular an air compressor.
  • the regulation system 38 comprises a valve 40 mounted on the fluid link 36, outside the enclosure 25, said valve 40 being switchable between a blocking state, in which it prevents the circulation of compressed gas between the source 34 and the pneumatic pump. 32, and a passing state, in which it allows the circulation of compressed gas between the source 34 and the pneumatic pump 32.

  • the fluid link 36 comprises an upstream section 37 between the source 34 and the valve 40, and a downstream section 39 between the valve 40 and the pump 22.
  • the valve 40 comprises a body 44 internally defining a passage 46 for the compressed gas, and a valve 48 movably mounted relative to the body 44 between a closed position, in which it closes the passage 46, and an open position, in which it releases the passage 46, the open position of the valve 48 corresponding to the passing state of the valve 40, and the closed position of the valve 48 corresponding to the blocking state of the passage 46.
  • the valve 40 further comprises a member 50 for returning the valve 48 to its closed position.

  • the body 44 also defines, at the junction between the upstream 56 and downstream 58 sections, a seat 70 for the valve 48 in the closed position.
  • This seat 70 is, in the example shown, formed by a shoulder surrounding the orifice through which the second channel 62 opens into the cavity 66.
  • the valve 48 is mounted movable in translation in the longitudinal direction L relative to the body 44 between its open and closed positions.
  • the valve 48 is, in the example shown, secured to a shaft 72 engaged in the second channel 62, said shaft 72 comprising a narrow section 74, of cross section less than 90% of that of the second channel 62 , and a wide section 76, of cross section substantially complementary to that of the second channel 62: the shaft 72 thus forms with the second channel 62 a guide for guiding in translation the valve 48 relative to the body 44.
  • the narrow section 74 is in particular interposed between the valve 48 and the wide section 76, the wide section 76 being at a distance from the valve 48 greater than the distance from the valve 48 to the first channel 60 when the valve 48 is in the open position, as visible on the Figure 2 .
  • the first channel 60 is not blocked by the wide section 76 when the valve 48 is open.
  • a seal 78 is disposed around the wide section 76, between said wide section 76 and the wall of the second channel 62. This prevents compressed gas from leaking out of the body 44 through the end by which the second channel 62 opens out of the body 44.
  • the valve 48 comprises an annular seal 80.
  • This annular seal 80 defines a face 82 for supporting the valve 48 against the seat 70 when the valve 48 is closed.
  • valve 48 is housed inside the cavity 66.
  • the return member 50 is, in the example shown, formed by a compression spring housed in the cavity 66, between the valve 48 and a bottom 84 of the cavity 66.
  • the valve 40 also comprises a metal counterplate 86 disposed outside the body 44 and movable jointly with the valve 48 so as to occupy a position close to the body 44 when the valve 48 is closed and a position away from the body 44 when the valve 48 is open.
  • the counter plate 86 is aligned longitudinally with the valve 48, the valve 48 being interposed between the seat 70 and said counter plate 86.
  • the counterplate 86 is in particular integral in translation with the valve 48. To this end, it is, in the example shown, made in one piece with a shaft 87 mounted, typically screwed, on the shaft 72, and extending through an opening 88 opening into the bottom 84 of the cavity 66 and outside the body 44. In particular, a seal 89 surrounds said shaft 87 in the opening 88 and provides sealing between the cavity 66 and the outside of the body 44.
  • the automatic pilot system 42 comprises a sensor 90 for monitoring a parameter, and an actuator 92 ( Figure 2 ) acting on the valve 40 to automatically switch the valve 40 from its passing state to its blocking state as a function of a signal produced by the sensor 90 and representative of the parameter monitored.
  • the sensor 90 comprises a first part 94 arranged in the confinement enclosure 25, and a second part 96 disposed outside of the confinement enclosure 25.
  • the first part 94 is capable of occupying a first state in normal time, and a second state when the monitored parameter verifies a predetermined condition, said second state being specific to the case in which said predetermined condition is verified.
  • the monitored parameter is here constituted by a state of the pump 22.
  • the predetermined condition is then that the state of the pump 22 is a predetermined state, typically constituted by a packed state of the pump 22.
  • the second part 96 is suitable for generating an electrical signal when the first part 94 is in its second state, and exclusively when said first part 94 is in its second state.
  • the second part 96 is suitable for generating an electrical signal when the predetermined condition is verified, and exclusively when it is verified.
  • the actuator 92 is electrically connected to the sensor 90 so as to receive said electrical signal when it is generated.
  • an electrical connection 98 electrically connects the actuator 92 to the sensor 90.
  • the actuator 92 consists of an electromagnetic suction cup, in particular an electromagnetic suction cup with permanent magnet, aligned longitudinally with the counterplate 86, the counterplate 86 being interposed between the valve 48 and the suction cup, said suction cup being arranged so that, when the valve 48 is in the open position, the counterplate 86 is pressed against said suction cup and that, when the valve 48 is in the closed position, the counterplate 86 is away from said suction cup.
  • the actuator 92 thus has, in the absence of electric current, an active state in which it exerts on the plywood 86 a magnetic force for biasing the plywood 86 towards its position pressed against the actuator 92 and, when it is supplied with electric current an inactive state in which it does not exert such a biasing force on the counterplate 86.
  • the return member 50 and the magnetizing force of the actuator 92 are dimensioned so that, when the counterplate 86 is pressed against the actuator 92, the biasing force exerted by the actuator 92 on the latter is greater to the return force of the return member 50.
  • the actuator 92 is thus able to retain the valve 48 in its open position, the biasing force forming, when the valve 48 is in the open position, a retaining force of the valve 48 in the open position.
  • the actuator 92 is suitable for automatically switch the valve 40 from its passing state to its blocking state when it receives the electrical signal generated by the second part 96 of the sensor 90.
  • the return member 50 and the magnetizing force of the actuator 92 are also dimensioned so that, when the valve 48 is closed, the biasing force exerted by the actuator 92 on the counterplate 86 is less than the force of return of the return member 50. Thus, the actuator 92 is not able to move the valve 48 from its closed position to its open position.
  • the regulation system 38 also includes, as visible on the Figure 2 , a button 100 with manual actuation for switching the valve 40 from its blocking state to its on state.
  • This button 100 is in particular formed by a push button aligned longitudinally with the valve 48, the seat 70 being interposed between the valve 48 and said button 100.
  • a simple press on the button 100 causes the valve 48 to move to the away from the seat 70 and, in this way, makes it possible to return the valve 48 to its open position.
  • the invention allows easy and economical retrofitting of existing installations, since it suffices to install the regulation system 38 therein.
