Title:
電磁式の圧力制御弁
Document Type and Number:
Japanese Patent JP4154120
Kind Code:
B2
Abstract:
In a proposed electromagnetic pressure regulating valve (10, 10a), the functional characteristics of a pressure regulating valve are combined with those of a switching valve. The pressure regulating valve (10, 10a) can be used in particular to control automatic transmissions in motor vehicles and is characterized by reduced manufacturing costs, reduced leakage and an operating range which is expanded for reduced operating pressures and with a continuous characteristic line. For this purpose, the valve part (11, 11a) of the pressure regulating valve (10, 10a) has a first seat valve (45) with a closing element (34). This closing element (34) cooperates with an actuating element (35, 35a) which has a control edge (50) to form a second seat valve (49).
