Definitions

  • valve body is provided with radial projecting connection pins engaged with annular piston means which displaces the valve body.
  • the present invention relates to a valve device, wherein the opening and closing functions take place under the influence of pressure medium, while the control of through flow and pressure may be controlled mechanically and/or by means of pressure medium.

  • At the one valve housing part there is at least one annular cylinder space, but for a communication opening for operating fluid, closed in the one axial direction and open in the other axial direction towards a space closed towards the outside.
  • annular piston means Inside the annular cylinder room there is an axially displaceable likewise annular piston means, upon introduction of pressure medium at the closed end of the cylinder means displaceable into the closed off space in order to engage connector means projecting from the valve body into said space in order to displace the valve body, against the action of spring means from its sealing edge engaging position so that through passage can take place.

  • annular cylinders and piston means instead of two annular cylinders and piston means, respectively, it is possible to use for the adjustment or set function utilize a mechanically operated device, such as a screw device axially engaging annular device movable to engage the connecting pins and abutments which according to the setting forms end stop allowing more or less displacement of the valve body or disc.
  • a mechanically operated device such as a screw device axially engaging annular device movable to engage the connecting pins and abutments which according to the setting forms end stop allowing more or less displacement of the valve body or disc.
  • Fig. 1 is an axial sectional view of an embodiment of the valve device according to the invention
  • Fig 2 is a perspective view showing the parts of the valve device separated from each other
  • Fig 3 is a perspective view of the valve disk or body
  • Fig 4 in a partially sectional view shows a modified embodiment of the valve device.
  • the valve housing as a whole includes the valve housing proper 1 , a so called cylinder part 2 and an enclosing jacket 3 as well as an end plate 4 , which also can be used as a wall securing means.
  • the valve housing proper is at one of its ends arranged to be connecting to a not shown channel or pipe for medium to be evacuated and inside a connection end opening 5 there is a valve chamber 6 having far larger diameter that said opening 5.
  • the valve chamber is radial defined by a wall 7 having a number of, preferably three, slots 8 open at the end edge 9 of the wall and extending a distance towards the opening 5.
  • control ring 10 having axially oriented slots 11 closed at the ends and having a defined length.
  • the slots 11 are arranged peripherally in a way similar to that of the slots 8.
  • a so called counter pressure ring 12 is arranged outside the control ring 7 . It preferably has a L-shaped cross section and a spring 14 is arranged between its projecting flange portion 13 and an abutment at the valve house part. The counter pressure ring is displaceable towards the said far end against the action of the spring 14.
  • springs 14a may be mounted . These spring have the same function as the spring 14.
  • the so called cylinder part 2 in the same way as the valve housing proper, has a central opening 15, the end of which is adapted to be connected with a pipe or channel.
  • the central opening in a direction inwardly ends at a seat 16 where a sealing ring of O-ring type is arranged.
  • the through flow or cross section area at the seat is considerably smaller that that of the valve housing part 1.
  • two annular grooves 18 and 19 serving as concentrically arranged cylinders.
  • the cylinder grooves 18 and 19 are accordingly open towards the valve housing part and closed at their opposite ends but for connecting openings or holes 20 and 21 for working or pressure fluid.
  • each cylinder groove 18 and 19 there is an annular piston means 22 and 23, respectively.
  • the annular piston means preferably at the closed cylinder end side includes a sealing ring 24 or 25 made of elastic material, and having a groove 26, 27 facing in the same direction so that the side portions 28, 29 defining the groove have a thickness reduced towards the ends so that they serve as piston seals.
  • the sealing rings are supported by and engage rigid annular pistons 30 and 31 , respectively, adapted to cooperate with the valve body designated 32 in a way explained below.
  • the valve body or disk 32 has a diameter far smaller than the free diameter inside the valve chamber 6, which means that as long as the disk is remote from the seat 16, a passage for the gas or the medium to be controlled will appear at the edge of the disk or body 32.
  • the disk 32 can be constructed in different ways and has an abutment edge 33 adapted to cooperate with the seat 16 of the cylinder part 2.
  • connection pins 34 e.g. by threaded bores at the edge of the disk or adjoining edge portion.
  • the connection pins 34 extend through the slots 8 in the wall 9 and through the slots 11 of the control ring 10. The extreme ends of the said pins will engage the side of the counter pressure ring 12 opposite to the spring 14 and consequently the spring strives to keep the valve disc engaging the seat 16.
  • the annular piston means 23 By introducing pressure fluid into, say, the inner cylinder 19, the annular piston means 23 will be displaced towards the valve housing part .
  • the spring 14 On removing the control fluid pressure the spring 14 will move the disk back to engage the sealing 16.
  • pressure fluid may be introduced into the outer cylinder 18, whereupon the piston means will engage the outer ends of the pins 34 and move the valve disk away from its sealing position. After having reached intended through flow position he pressure medium supply may be closed so that the enclosed fluid volume serves as a stop against the return movement of the piston means and consequently total closing of the valve.
  • a pre-setting of the possible movement of the valve disk 32 may also be achieved by means of a set screw 35. By turning the screw inwardly or outwardly at the front and of the valve house part the end position to be reached by the control ring 10 may be defined.
  • the valve arrangement can as already mentioned be controlled by means of pressure medium. This normally is air but also other pressure mediums or fluids can be used.
  • the control device proper can be manually or automatically operated, i.e. connected to the evacuation unit to be controlled so that the valve will open on demand, where there is a need to evacuation. At narcoses masks the control device for example may be arranged to be controlled by the valve device controlling the supply of anaesthetic gas. On diathermy instruments the control device for the valve may the controlled inductively by the current supply to the instrument. The same goes for laser instruments and other electrically operated instruments.
  • the control device may include one manually and one automatically operated part, the former controlling the pressure fluid to the valve cylinder device defining the end position of the valve disc, i.e. defining if there is a need for a minimum through flow and the rate thereof.

Abstract

L'invention concerne un système de soupape utilisé de préférence pour réguler le flux provenant d'un dispositif d'évacuation. Ledit système de soupape comprend une cage de soupape, des ouvertures de connexion et un canal d'écoulement, ledit canal comprenant une section plus large dans laquelle le corps de soupape peut être déplacé dans le sens axial et disposé de sorte, dans une position spécifique, à entrer dans une arête d'obturation et d'about. L'aspect novateur de l'invention réside dans le fait qu'à une face terminale d'une section de la cage de soupape renfermant une des ouvertures de connexion, il est prévu au moins un cylindre annulaire sous forme de rainure axiale, ladite rainure annulaire ou ledit cylindre étant sensiblement fermé(e) à l'extrémité opposée s'ouvrant en direction de la section plus large du canal. Ledit cylindre annulaire contient un élément annulaire de type piston, destiné, lorsque le milieu de pression est introduit dans le cylindre annulaire, à l'extrémité généralement fermée du cylindre, à être déplacé vers l'extérieur, afin d'être en prise avec des broches de connexion au niveau du corps de soupape et à déplacer ledit corps de soupape à l'encontre de la force exercée par un élément à effet ressort, pour le faire sortir de sa position d'étanchéité.
