Definitions

  • the object of the invention is to considerably increase the life of these control members by disposing them in a separate chamber which is tightly closed against the entrance ot ushing water and may be filled with air or a liquid oi any consistency. It desired, the pressure in the chamber may be lower than that oi the atmospheric air. Preferably the chamber may be nlled, wholly or partially with a lubricant as oil or iat.
  • Figs. l tot show .a modication axial displacement is locked in the end position'by resilient ring segments.
  • Figs. l. and 2 are vertical cross-sections of the device in dierent positions;
  • Figs. 3 and 3l show, in plan view and in vertical crosssection respectively, a detail.
  • the valve rod is locked by a resilient ball-ring,
  • Fig. 4 beingr a vertical cross-sectional view, and Figs. 5 and 5 a in which the respectively.
  • Figs. 6, 'I and 'il show a modiiication similar to that illustrated in Figs. 1 and.2 in which the axial displacement oi the valve is locked by spring rings.
  • Fig. 6 is a verticalcross-section, Fig. '1 a detail, partly in vertical cross-section and Fig. 'l a plan view.
  • Fig. V8 isan elevation, section showing a totalview ot its accessories.
  • Fig. l i is the tubing carrying the piston 2, on which the cylinder slides up wards or downwards.
  • e piston 2 is made hollow to form a valve chem er l in. which the valve il is located..
  • the side wells et the chamber are clowords continued to tor-'rn e. tube l oi somewhat smaller diameter then the cylinder t.
  • the tube l is closed at its end by e. screw pluglc and on this is screwed a.
  • the tube .”l enclosfesI the control members thereby valve rod is provided witha collar it forming at its upper and its lower side irustums of cones.
  • These conical surfaces oooperstevlith ring segments il touching with conical outer faces the conical inner ieces of the ring l2 resting on the spring i3.
  • the cylinder l occupies its lov/est position andthe valve is closed.
  • "libe 'ring segments il lle on surface oi” the collar l@ thus locking the same. illl'hen water enters the cylinder through the openings lll in the tubing the cylinder is lifted and the spring is compressed.
  • the ring segments il hereby ottoin position lil so that the opened valve is loclred.
  • New the water ilotvs ori, the vcyiimlcr releeseol again.
  • the spring i3 is released to such en extent that the hydraulic pressure acting upon the valve together with the spring l@ displaces the valve rod il against the resistance oi the ring scontento ⁇ l l downwards;
  • an auxiliary valve I9 is actuated by the -valve rod 8 whereupon by .the variation of the hydraulic pressure conditions the main valve 5 is opened, and a further diiierence consists therein that a pin or bolt 20 is inserted between y the spring '9 acting toopen the valve, and the Y cylinder 3 whereby the stroke ofthe valve can be regulated and the duration ofthe rigid connection between the control members may be reduced to a small fraction of a second.
  • the diameter of the control rod 8 is, in the casing conilned .by the parts la, l' and 1b, increased to such an extent that a piston forms which is provided at its circumference with conical faces 29.
  • On these faces slide spring rings 80 having interior conical faces and being inserted between rings 3
  • are secured to the parts 'la or 1b respectively.
  • the head 32 of the valve rod is connected with the lower end of the valve 5 in such a manner that a small play is provided between the ends facing each other.
  • holes 33 are bored through which oil is circulated. When the .piston of the rod 8 reaches its end positions. the holes are closed and an impact of metal against metal is prevented.
