Abstract
An electromagnetic valve for controlling a passage for a flow of fluid or for a difference in the pressures between an inlet (48;56) and an outlet (56;48), comprises a body (10;16;46) on which is arranged a solenoid coil (22), a bore (26) in which is slideably mounted valve member (30) progressively displaceable in response to actuation of the solenoid coil (22) between a first position and a second position. The valve member (30) and the body (46) comprises cooperating valve surfaces (54;62) defining the passage. One valve surface (62) has in axial section a variable profile so that the area of the passage, in a radial section is a predetermined function of the intensity of the current applied to the solenoid coil (22).
