    This invention relates to an actuator for a moving contact of an electric switch KIY A-oh 75 switches. The purpose of the invention is to increase the reliability and simplify the design. A hydraulic hydraulic cylinder has a floating end damping ring 21, into which the damping element 20 passes, which is rigidly connected to the piston 2, and the specified piston does not have any reinforcement fitting to the housing 1. The ring 21 carries two protrusions 26 and 28, (forming a double sealing valve with respect to the surface 29 of the piston 2 and the surface 30 of the housing base. At the end of the stroke of the piston, the ring forms a double valve that seals the hole 6. 6. Cp. 5 Il. G "(L

    Claims (9)
    [1]
    Claim
    1. Differential hydraulic power cylinder for an oil-pneumatic drive of an electric switch, comprising a cylindrical body, a piston with a rod mounted in the body and a rod and rodless chambers bounding it, the rod connected to the moving contact of the switch, the rod chamber communicating with a source of fluid under pressure, and the rodless chamber communicates with a source of fluid under pressure or with a drain through an opening made in the corresponding base of a cylindrical housing a damping ring mounted for movement in a rodless chamber around said hole, a damping protrusion made on the piston from the rodless chamber and entering the ring at the end of the stroke of the piston, distinguished by the fact that, in order to increase reliability and simplify the design, The piston is installed in the housing with
    a gap for communication rods and rodless cavities, and on the radial surfaces of the ring are seals that interact, respectively, with the end surface of the piston and the base of the housing, and each seal ring, organizing the stroke of the piston, covers an area larger than the cross section of the rod.
    [2]
    2. Cylinder pop. 1, characterized by the fact that the seals are made in the form of annular projections, which are part of the ring.
    [3]
    3. The cylinder according to claim 2, about tl and h a-. This is because the ring with its protrusions is made of a more solid metal than the piston and the base of the cylinder.
    BUT - ·
    [4]
    4. Cylinder in accordance with claim 2, 3 or 3, that is, because the area bounded by each protrusion is 50% larger than the stem section.
    [5]
    5. Cylinder pop. 4, characterized in that the projections are limited to identical areas.
    [6]
    6. Cylinder pop. 4, characterized in that the annular space bounded by the piston with its protrusion, and the ring with its protrusion interacting with the piston, is communicated with means for additional feeding from the source of fluid under pressure.
    [7]
    7. The cylinder according to claim 6, of which T and l with the fact that the means for additional powering include
    in itself executed in the damping protrusion of the axial channel and communicated with him. radial channels, check valve mounted in the axial channel.
    [8]
    8. Cylinder pop. 7, characterized in that opposite the radial channels on the inner side of the ring is made Chamfer.
    [9]
    9. The cylinder of π. · 8, which differs from I by the fact that on the inner side of the ring there is an additional Chamfer symmetrical to that indicated.
    1 10. The cylinder according to claim 9, which differs with I in that the cross section of the damping protrusion is larger than the cross section of the rod.
