초록 ▼

Adjustable flow electromagnetic valve having a closing assembly (8) movable within a chamber (7) with a passage (3) linked to a high pressure area and a passage (4) linked to a low pressure area. The electromagnetic valve is designed such that the closing assembly consists of a valve (8) freely movable within the chamber (7). The disk-shaped valve (8) is flat, light and non-deformable and is capable of being automatically brought to its fluid flow position when pressure within the inlet passage (HP) (5) tends to a value approaching a predefined set pressure; the electromagnetic valve is also designed such that fluid flow through the valve (8) is achieved by openings (10) formed in the thickness of the valve, the openings being arranged in a median area outside the circumference of the inlet passage (3) so that the latter can be closed when the valve (8) is electromagnetically returned. It is further characterized by adjusting the electromagnetic return force exerted by the electromagnet for placing the valve (8) at a predetermined point between opening and closing to provide a predetermined constant flow, and for alternately shifting it, according to a predetermined frequency, to provide an adjustable alternating flow of the same frequency and of variable amplitude, resulting in sequential, pulsed, rhythmic operation.

An adjustable flow solenoid valve, which operates without a return spring, allowing connection of two circuits maintained at different pressures, in order to ensure flow of a fluid from a high pressure zone (HP) to a low pressure zone (BP), of the type comprising: a casing (2) constituting a chamber (7) into which opens an inlet conduit (3) having an orifice connected to the high pressure zone (HP), and an outlet conduit (4) connected to the low pressure zone (BP); a closure assembly that can be moved inside said chamber and which: under the action of an electromagnetic force, tends to close the orifice (5) of the inlet conduit (3), in the absence of the electromagnetic force, is returned toward the outlet conduit (4) and does not close the entry of the outlet conduit so as to obtain, in this position, a continuous flow of the fluid with a maximum flow rate maintained at a predetermined level that is a function of the pressure difference between the high pressure zone (HP) and the low pressure zone (BP) and the pressure drop, such that in the absence of the electromagnetic force: the closure assembly consists of a flap valve (8) that can be moved freely inside said chamber (7), which flap valve is in the form of a nondeformable lightweight flat disk that can be returned automatically into its position permitting the fluid to flow when the pressure inside the inlet conduit (5) tends toward a valve close to a predetermined set pressure; the flow of the fluid through the flap valve (8) is obtained by means of orifices (10) made in the thickness of the flap valve, which orifices are arranged in a central zone outside the periphery of the inlet conduit (3), so that the inlet conduit can be closed when the flap valve (8) is returned under the action of the electromagnetic force; means are included for adjusting the electromagnetic return force exerted by the electromagnet, allowing said valve (8), on the one hand, to be positioned at a predetermined level between opening and closure in order to obtain a constant predetermined flow rate and, on the other hand, to be moved in alteration, at a predetermined frequency, thus allowing an alternating flow rate of the predetermined frequency and of an adjustable amplitude of flow to be obtained, leading to sequential, pulsed and rhythmic operation.
