  • Said rollers (5, 6) each cooperate on the one hand with said shaft (4) and on the other hand respectively with a piston (7, 8) movable in translation along an axis oriented along the second direction A '.
  • a first piston (7) is subjected to the action of return means and a second piston (8) separates two hydraulic chambers (9, 9 ') connected by a conduit system (18).
  • the case has an overall length of about 35 cm; the housing (2) has a width of about 3.5 cm and a height about 4.2 cm and the cylindrical tube (3) has an outside diameter of about 3.5 cm.
  • said return means comprise a plurality of identical or different Belleville washers (10) mounted substantially coaxially along said second direction A '.
  • said Belleville washers (10) are mounted on a central guide tube (11) whose axis coincides with the axis of the cylindrical tube (3).
  • 100 identical steel washers each having an outside diameter equal to 32 mm and an internal diameter equal to 16 mm, have been arranged for a height of 2 mm, all in simple opposition, that is to say with the concavities of the adjacent washers in opposition.
  • This arrangement has made it possible to obtain a piston stroke (7) of the order of 10 cm.
  • the durability of the return means is increased because the tests conducted have shown that return means composed of Belleville washers can reach one million cycles without significant loss of characteristics, while a helical spring of equivalent size does not exceed 500 thousand cycles without significant loss of characteristics.
  • a Belleville washer also called “spring washer” is, in known manner an annular washer, generally made of metal or metal alloy, having an inner diameter and an outer diameter, the inner diameter being less than the outside diameter, the annular shape being not flat but conical. A Belleville washer thus extends over a height greater than the thickness of the material constituting the ring.
  • a Belleville washer depends on the compressive force to which it is subjected. This compression is usually oriented parallel to the axis of the annular shape. Generally, a Belleville washer is made of an elastic material and it resumes its original height when it is no longer subjected to a compressive force.
  • the washers that were chosen all had the same inside diameter and the same outside diameter, the same thickness and the same height at rest.
  • washers that all have the same inside diameter but some have a different outside diameter, and possibly a different thickness and / or height.

  • the latter is preferably mounted at an upper end on a tubular needle bushing (24) and at a lower end on a bearing (20), for example a bearing ball.
  • the distal end of the housing that is to say the end farthest from the shaft (4), is provided with a thread on the inner face of the cylindrical tube (3).
  • This thread is intended to allow to screw a distal plug (21) having on its outer surface a complementary thread.
  • a hardened steel washer (22) is positioned at each end of the return means to prevent premature wear of the contact surface on the one hand of the distal plug (21) and on the other hand of the piston (7).
  • the piston (7) is provided at its periphery with an O-ring (23) in contact with the inner face of the housing (2), to prevent the oil in the chamber (9) from propagating in the cylindrical tube (3).
  • the piston (7) is thus in contact at a first end with respect to the direction A 'with a washer (22) and at the other end with the roller (5).
  • An O-ring (19) is also positioned around the shaft (4), at the top cap (25) which holds the inner part of the shaft (4) in the housing (2).
  • the proximal end of the housing that is to say the end closest to the shaft (4), is also provided with a thread on the inner face of the housing (2). This thread is intended to allow to screw a proximal plug (26) having on its outer surface a complementary thread.
  • the piston (8) is also provided at its periphery with an O-ring (27) positioned in the inner face of the casing (2), to prevent the oil in the chamber (9, 9 ') from propagating respectively in the other chamber (9 ', 9) without passing through the ducts (18) formed in the wall of the housing (2).
  • the piston (8) is thus in contact at a first end with respect to the direction A 'with the roller (6) and at the other end with the chamber (9').
  • a spring (16) is positioned in this chamber (9 '), substantially coaxial with the direction A', between the face of the piston (8) and the face of the adjacent proximal plug (26).
  • a safety valve (17) is also positioned between the two opposite faces of the piston (8) with respect to the direction A 'to allow passage of the oil from the chamber (9') to the chamber (9) in case of overpressure.
  • a nonreturn valve (15) is also positioned between the two opposite faces of the piston (8) with respect to the direction D, visible on the figure 6 .
  • the two ducts (18), visible Figures 4 and 5 are each provided with a needle (28) for regulating the flow of oil and therefore the speed of return of the door in its closed position (0 °) and each have at their end opening on the outer face of the housing (2) a locking ball (29).
  • a filling plug (30) is used to fill the oil door closer through the housing wall (2).
  • the second variant, illustrated figure 7 to 9 differs from the first essentially by the positioning of the non-return valve (15), the number of springs (16) and the absence of a filling plug (30), as can be seen by comparing the figures.
  • the door closer (1) allows the opening of the door in both directions of opening, from 0 ° to 180 ° and causes its automatic closing. However, it is obvious that it can also be used for a door that opens only in one direction and at a smaller angle, for example 90 °.
  • the force of the door closer can be adjusted from 3 to 5 (according to EN1154) by means of a set screw on which it is possible to operate, for example with a hexagonal key.
  • the closing speed can be set in two ranges: from 0 to 25 ° for the end position; from 0 ° to 180 ° over the entire closing range.
  • Step one Opening the door
  • the door is taken directly on the axis of the door closer.
  • the opening of the door drives the shaft (4) in rotation. This rotation causes the translation of two pistons (7, 8), via the two rollers (5, 6).
  • the piston (7) moving comes to compress the damping means consist of washers (10) of the type "Belleville" assembled heads spades.
  • the stack of washers is preloaded before mounting the device.
  • the return means relax and exert on the piston (7) a force similar to that of the opening, but in the opposite direction.
  • This force exerted on the roller (5) induces a torque on the shaft (4) via the cam profile and this torque causes the closing of the door.
  • the triggering pressure of the valve is obtained by design: no calibration necessary, the stiffness of the spring of the valve, its length in load and the surface of passage of the oil define this pressure.
  • the choice of closing means is simplified as a function of the desired torque. Indeed, knowing the compressive strength values of each washer, it is possible to realize the return means by selecting a plurality of identical or different Belleville washers (10) and substantially coaxially mounting said Belleville washers (10) in said second direction A ', said selection and said mounting being operated according to the desired force exerted by said means recall on said first piston (7), integrating, for example the weight of the door or an average weight.
