1. A solenoid valve type device, with a slide mechanism reactive to pressure, the device comprising:
a body comprising at least 3 liquid flow channels;
means forming a slide that can be displaced in said body by a fluid under pressure, between a first position in which there is fluid communication between a first channel and a second channel among said 3 flow channels, and a second position in which there is fluid communication between said second channel and a 3rd channel;
means of selecting an activation pressure threshold for a displacement of said slide, among at least one first pressure threshold (Ph) and at least one second pressure threshold (Pb, in which Pb<Ph);
means of regulating said at least one first pressure threshold (Ph) and said at least one second pressure threshold (Pb) for activation of said slide.
