Abstract
A solenoid valve device with a pressure-responsive slide mechanism, including: a body including at least three channels for flow of a liquid; a slide that can be moved in the body by a pressurised fluid, between a position with fluid communication between a first and a second channel among the three flow channels, and a position with fluid communication between the second channel and the third channel; a selector for selecting an activation threshold for movement of the slide, among at least one first and at least one second pressure threshold; and a regulator for regulating at least the activation thresholds of the slide.
