  • FIG. 4 shows an application of the device to a hinged closure.
  • the device as a whole is indicated at l and comprises a tubular con tainer 2 closed at the ends thereof by caps 3 and 4. To cap 3 is secured. through bolt 5. the tang of an extension 7 with which. as will be more evident from FIG. 4, the device is hinged onto the inside surface of vertical jamb 8 to which is further hinged the hinged closure 9 (for example. a gate) which is to be opened or closed. From jamb 8 bracket 10 juts out to which is articulated along a vertical axis a piece I] to which. in turn. said extension 7 is pivoted by means of pivot pin I2 whose axis is perpendicular to said vertical axis.
  • the hinged closure is provided with a tongue 13 for connection'to the other end of device 1, which end consists of a piece 14 screwed onto the threaded portion of shaft 15 and rotatably joined to said tongue 13 by means ofa pin 16.
  • Shaft 15 is guided in seal-tight manner in cap 4 and. as will be seen further on, can be pushed forward or withdrawn within the container 2 in such a manner as to produce a lengthening or shortening of device I and therefore a swinging of hinging closure 9 around its hinged axis from the position indicated by the solid line to that indicated by the broken line in FIG. 4.
  • an electromotor 17 whose shields l8 and 19 support the stator 20 and. through means of bearings 21 and 22, shaft 23 of rotor 24.
  • a cavity is formed in disc 30 in which there are two meshing gears 31 and 32 constituting a hydraulic pump.
  • Gear 32 is rotatably secured. to pin 33 which is connected to shaft 23 by means of a joint of cross-type which comprises a ring 34, keyed onto pin 33 by means of a key and locked axially by bolt 35, which is provided with radial arms 36 arranged cross-wise and extending into recesses formed in the adjacent hollow portion of shaft 23.
  • the oil leading out along pin 3 is prevented by seal-ring 37 to pass into electromotor l7 s and discharged into well 26 through hole 38. In this way pin 33 is lubricated at the same time.
  • the oil which lubricates pin. 39 which supports gear 31 is discharged into well 26 through hole 40.
  • the feeding and return conduits of the pump are indicated as 41 and 42 and lead, on one side, into the chamber in which gears3l and 32 rotate in opposed points of said chamber with respect to the vertical plane passing through the pins 33 and 39 and, on the other side, into a cylindrical cavity 43 formed perpendicularly to the longitudinal axis of the device in a posite end, into cap 4 and is locked against any possible rotation by ring-nut 47.
  • Piston 48 which slides in cylinder 45 divides the same 45 into two chambers 49 and 50 and is fixed onto shaft 15 previously mentioned.
  • valve 51 oil inlet hole into the interior of cylinder 45 is shown as 51 and its connection with the feeding conduit 41 is controlled by a valve-of non-retum type or check valve 52.
  • Said valve comprises a nipple 53 screwed into the cavity 43 and containing a spring 54 which forces with one end a small ball 55 against an orifice 56 and abuts with the opposite end on a plug 57 screwed into the.
  • the joint between small pipe 59 and block 44 is accomplished through means of a nipple 60 screwed into cavity 43 and in which several holes 61 are provided.
  • a small piston 62 is slidable in said cavity 43. This piston is movable between the openings of the conduit 41,42 into said cavity 43 and is provided on its opposite ends with protuberances 63 and 64 designed to act against small ball 55 through orifice 56 or, alternatively, to come to rest against nipple 60, in this last position however permitting the oil to pass through the holes 61.
  • Conduits 41 and 42 (see FIG. 3) further communicate, respectively, with passages 65, 66 and 67, 68 along which are located relief valves 69, 71 and check valves 70, 72 of a type substantially similar to that mentioned above as 52, of which relief valves 69, 71 are designed to open when the oil pressure in pipes 41, 42 exceeds a pre-established value, while check valves 70, 72 open when a decrease in pressure occurs in conduits 41, 42 with respect to well 26.
  • valves 69, 71 are adjustable through the provision of adjusting plugs 73, 74 which, may be screwed more or less in disc in order to, vary the force with which the little springs press the respective small balls against the adjacent orifices.
