  • the shaft 76 would have to be rotated in the direction U1 before the pin 45 and the driver 71 are brought into engagement, so that the driver arrives behind the pin 45.
  • the shaft can then be axially displaced again, engaged with pin 45 and the orifice rotated in the direction of U2.
  • the drivers 71 are arranged on the shaft 76 at regular intervals. Since each of the valve members 12a to 12h should be individually controllable, the pins 45 in the various panels 40a to 40h of the valve members 12a-h are attached to different receptacles 42a to 42h. It can thus be determined via the axial position of the shaft which valve member 13 is actuated. In a first axial position, for example, the orifice for the valve member 12a can be controlled, since in this position the drivers 71 can be brought into engagement with the orifice 40a for the valve member 12a. In this axial position, only the aperture 40a can be controlled. The remaining panels have their pins at other positions, so that the corresponding drivers 71 turn empty when the valve member 40a is actuated.
  • the diaphragm 40b for the valve member 12b is controllable, since in this position one of the participants 71 can be brought into engagement with the corresponding pin 45 of the diaphragm 40B of the valve member 12B.
  • This also applies analogously to the other valve members 12 c to 12 h.
  • none of the valve members can be actuated by the shaft 76. In this position, the shaft can be freely rotated and a rotational position of the shaft can be selected in order to determine in which direction a valve member should be actuated.
  • two valve members can be controllable in the first axial position.
  • the pins 45 are arranged in the diaphragm between the two valve members 12 in the same position offset by 90 ° (see the empty series 42a-h in FIG. 4A). If the first valve member is to be actuated, the shaft 76 is first brought into a corresponding rotational position and then axially displaced until a driver 71 overlaps with the corresponding pins 45. For the control of the second valve member, the shaft must first be moved back again, rotated by 90 ° and then returned to the first axial position. In an axial position, several valve elements can be controlled simultaneously. An example of such a rotary selection is shown in patent application EP 1 515 073.

Selon un premier aspect, la présente invention concerne un agencement de soupapes à plusieurs voies (M) destiné à réguler le débit d'un fluide. L'agencement de soupapes comporte au moins un premier et un deuxième élément de soupape (12a-h) et des moyens d'actionnement (70) destinés à actionner les éléments de soupape (12a-h). Les éléments de soupape sont disposés de telle sorte qu'au moins un élément de soupape prédéterminé (12a) peut être sélectionné et actionné en fonction de la position des moyens d'actionnement (70). Les moyens d'actionnement (70) sont agencés de manière à pouvoir coulisser en translation. Le premier élément de soupape (12a) peut être actionné dans une première position de translation des moyens d'actionnement (70) et le deuxième élément de soupape (12b) peut être actionné dans une deuxième position de translation différente de la première.
