Definitions

• the device according to the present invention makes it possible to effectively remedy the aforementioned drawbacks, in particular by means of a deformable element ensuring the balance between the pressure existing inside the housing and the external pressure.
• the invention also relates to means relating to the adjustable connection between the boat and the body of the jack as well as to the connection between the rod and the body of the latter.
• the invention further relates to electrical switching means constituted by blades of magnetic material.
• flexible such as Reed switches, slaved to the position of a magnet disposed outside the housing, so that the only points to be made completely sealed are those through which the connecting wires pass to the current source. .
• the cylinder housing can be favorably formed of a hollow profile developed longitudinally and feimé at each of its ends by plugs which can be determined in a standard manner whatever the longitudinal development given to the body of the housing.
• Figures 1 and 1A show an embodiment of the deformable element.
• FIGS. 2 and 2A show an alternative embodiment.
• Figures 3, 3A and 3B show an embodiment of a cylinder housing according to the invention and its means of adjustment and fixing in position.
• FIGS. 4 and 4A represent electrical switching means provided for controlling the operation of the jack.
• FIG. 5 schematically recalls how the connection between the pilot cylinder and the tiller and the boat is established respectively. It allows a better understanding of the FIG. 3 and FIGS. 6 and 7 which represent variants of the adjustment and fixing means in position shown in FIG. 3.
• Figure 1 shows schematically in section a cylinder whose housing is designated by the reference 1 and inside which is housed a deformable element 2 in the form of a bellows. This deformable volume is connected to the ambient air through an orifice 3.
• the reference 4 designates the jack rod made integral with the thread 5 slaved to the conventional movement control assembly (not shown).
• Figure LA shows in perspective the demountable volume 2 in the form of a bellows.
• FIGS. 2 and 2A represent a variant according to which the deformable element consists of a flexible membrane 6 housed in a cutout 7 made in the housing 1. This membrane is protected by a grid 8.
• FIG. 3 represents a jack housing produced in accordance with the invention and its means for adjusting the position and fixing.
• the housing 1 is constituted by a hollow section developed longitudinally, closed at its ends by plugs 1a and 1b. In this housing are practiq ⁇ ées on either side of the grooves 9 (of which only one is visible in the figure).
• the pivot support 10 of the U-shaped cylinder is provided at the end of each of its branches with a sliding pin 11 movable along the groove 9 forming a slide.
• a symmetrical arrangement exists on the non-visible part of the housing.
• FIGS. 3A and 3B show on different scales, respectively in perspective and in section, the method of mounting the sliding studs and the connection with the housing.
• the pin 11 is integral with the plate 12, itself integral of the sliding plate 13 by means of the screws 14.
• the longitudinal movement of the plate 13 is limited by the plugs 1a and 1b of the housing.
• the tightening of the plate 12 on the plate 13 by means of the screws 14 ensures the locking in position of the assembly.
• Figures 4 and 4A show, on a different scale, switch-switch means with flexible blades, such as Reed switches, slaved to a magnet.
• a plurality of these switch-switches and corresponding magnets can be provided to ensure start-up, shutdown as well as various other switches.
• a cover 18 in which a suitable form of recess 19-19 'is made so as to allow the insertion and maintenance of the button 20 and the magnet 21 integral with each other.
• This switching element is fixed on a plate, such as on a printed circuit 25, said plate being -Even fixed inside the box Depending on whether the magnet 21 integral with the button 20 is facing or not superimposed on the switch 22, the contact between the blades 23 and 24 is ensured or not. It is obvious that the switching can be reversed according to the corresponding provision.
• FIG. 5 intended to recall the relative movements of the various members, schematically indicates how the connection of the pilot cylinder is established respectively to the bar and to the boat.
• the reference 26 designates the frank ba and the reference 26 & the axis of rotation of the rudder that it drives.
• the rod of the jack 27 whose housing is designated by the reference 28 is connected in 2 ⁇ b to the bar, while the articulated pivot 29 support of the jack is rotated in the support 30 secured to the boat. Under these conditions, when the rod 27 leaves the housing 28 or returns inside the latter, the bar is moved decently each side relative to the median axis (bar position at zero).
• FIG. 3 represents a sliding means making it possible to obtain this result, the same is true of FIGS. 6 and 7.
• the reference 31 designates the casing of the jack (referenced 28 in FIG. 1), and the reference 32 denotes the control screw penetrating into the threaded tubular rod 33 of the jack (referenced 27 in FIG. 1).
• an element 34 integral with the tube 33 and provided with ears 35 and 36 respectively forming slides housed in the slides which constitute the ribs 37 and 3d respectively on the one hand, 39 and 40 d ' on the other hand, arranged longitudinally on the interior walls of the housing 31.
• This element 34 therefore prohibits the axial rotation of the rod 33, which causes the latter to slide to produce the effects required when the screw 32 is rotated.
• the housing 31 is provided with a longitudinal projection 41 with a T-section.
• the part 42 constituting the articulated pivot supporting the jack (referenced 29 in FIG. 5) provided at its upper part with a yoke 43 is attached to the boat.
• the connecting means between the part 42 and the housing 31 include the two parts 44 and 45 in which are formed grooves 46 and 47 provided to allow the sliding of these parts along the projection 41.
• the parts 44 and 45 are drilled to allow the threaded bolt 48 to pass, which rotates the yoke 43 loosely, and they are immobilized on the housing 31 by means of the knurled nut 49 and the threaded bolt 48.
• Parts 44 and 45 are provided at their lower part with additional L-shaped projections, so that said parts can be immobilized on projection 41 with a pinching effect, which makes it possible to considerably reduce the effort of tightening by means of the bolt 48 and the nut 49.
• the parts 44 and 45 are dimpled at 50 and 51, dimples in which the part 42 can move .
• FIG. 7 which represents an alternative arrangement, the bolt 48 of FIG. 6 is replaced by an axis designated by the reference 52.
• This axis is threaded at one of its ends to receive the nut 53 "while its other end is formed by the part 54 in which a perforation is made.
• the fixing in place of this axis is determined as follows: a screw or a key 55 is provided for joining the end 54 of the axis 52 to the part 56 in which is formed a recess for the housing of the part 54 of the axis 52.
• An eccentric hole 58 is made in the part 56, the locking position of which is shown in solid lines.
