Title:
ELECTROMAGNETICALLY ACTUATABLE VALVE SYSTEM AND VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO2002025153
Kind Code:
A3
Abstract:
The invention relates to a combined valve device (1) comprising two electromagnetically actuatable valve systems (2, 3). Each valve system (2, 3) comprises an actuating device (4.1, 4.2), a main valve (9.1, 9.2) which is arranged between an inlet chamber (17.1, 17.2) and an outlet chamber (18.1, 18.2), and a pilot valve(8.1, 8.2), the main valve element (10.1, 10.2) and the pilot valve element (12.1, 12.2) forming one structural unit (13.1, 13.2). The inventive device comprises at least three connections (22, 23, 24) coupled to the chambers (17.1, 17.2, 18.1, 18.2) of the valve systems (2, 3), the inlet chamber (17.1) of the first valve system (2) being coupled to a pressure medium source, the outlet chamber (18.1) of the first valve system (2) and the inlet chamber (17.2) of the second valve system (3) being coupled to at least one consumer, and the outlet chamber (18.2) of the second valve system (3) being formed by a discharge chamber. According to the invention, the inlet chamber (17.2) of the second valve system (3) and the outlet chamber (18.1) of the first valve system (2) are formed by a working chamber. The fixed seat (11.1, 11.2) of each main valve (9.1, 9.2) is formed by an inset (34.1, 34.2) which can be fixed in the housing of the valve system (2, 3), and the partition wall (29) between the two valve systems (2, 3) is formed respectively by one of the insets (34.1, 34.2) of said two valve systems (2, 3).
