Title:
ELECTROMAGNETIC VALVE
Document Type and Number:
WIPO Patent Application WO/1995/020739
Kind Code:
A1
Abstract:
The proposed electromagnetic valve comprises a housing (1) with a seat (2) which is covered by a cut-off unit (20). The valve also has an electromagnetic actuator with a magnetic circuit (3) provided with lower (4) and upper (5) flanges, and with a sealing dividing tube (7). The tube (7) has a third section (32) made of a ferromagnetic material and arranged beneath the section (31), which is made of a slightly magnetic material and situated opposite the lower flange (4) of the magnetic circuit. The mean diameter of the valve seat (2) is equal to the internal diameter of the third section, and a non-metal annular seal (25) of the core (24) is situated opposite the third section of the sealing dividing tube and below the lower flange (4) of the magnetic circuit at a distance equal to or greater than the travel distance of the core. The seat (2) has a ring projection (33) which is triangular in cross section and has a symmetrical profile with a curvature (34) at the apex.
