SWITCHABLE PRESSURE-LIMITING VALVE

A switchable pressure limiting valve with an electromagnet (1) and with a device (2) for opening and closing a passage for the fluid stream. The opening of the valve is determined by the balance of forces at the tappet (3) upon which the pressure force of the fluid at the P-connection (4), the press...

Beschreibung
Zusammenfassung:	A switchable pressure limiting valve with an electromagnet (1) and with a device (2) for opening and closing a passage for the fluid stream. The opening of the valve is determined by the balance of forces at the tappet (3) upon which the pressure force of the fluid at the P-connection (4), the pressure force of the fluid at the T-connection (13) and the forces of two springs (5) and (6) act. The force of the spring (6) is varied by means of the position of the armature of the electromagnet. When the pressure force at the P-connection (4) outweighs the sum of the other forces, the valve opens. The above-mentioned device for opening and closing is composed of a diaphragm (7) and of a sealing seat (12), and this diaphragm is tension-mounted sealingly between the magnetic pole (10) and the housing (21).
