Abstract: A method of manufacturing a valve element for a solenoid valve to open and close a valve seat, comprising the steps of; preparing a leaf spring including an outer peripheral ring section and a hub section having a central hole, forming a ring-shaped outer peripheral seal along the peripheral ring section, and preparing a movable core having a cup-shaped cross section and including a cylindrical section and an end wall section. The method further comprising, forming a valve seal on the end wall section by placing the movable core and the leaf spring in a mold and aligning and holding the leaf spring and the stepped section in contact with each other, and aligning a holder ring along an outer periphery of the movable core, and bringing the holder ring into engagement with the movable core, wherein the leaf spring and the movable core are rigidly secured to each other.

Abstract: A valve element with a disk-shaped leaf spring carrying a movable core in a solenoid valve to open/close a valve seat. The leaf spring includes an outer peripheral ring section, a hub section having a central hole and a plurality of radially arranged arm sections connected between the ring; section and hub section. A seal of elastic material extends along the outer peripheral, ring section of the leaf spring. The movable core has a cylindrical section and an end wall section having a through central hole. The cylindrical section has a stepped section on its outer periphery adapted to be held in contact with the leaf spring. A valve seal is formed on the end wall section through vulcanization and molding, and has a main body section on the outer surface of the end wall section, a small diameter section in said through hole and a holder section connected to the main body section by the small diameter section and inner surface of the end wall section.

Abstract: A valve element comprising a leaf spring carrying a moveable core to open and close a valve seat in a solenoid valve. The leaf spring includes an outer peripheral ring section, a hub section with a central hole, connection holes, and a plurality of radial arm sections. An outer peripheral seal is arranged along the outer peripheral ring section. A valve disk is fitted to the hub section with a valve seal to contact the valve seat. A movable core with a flange section is on the outer surface of the hub section. A holder ring is connected to the valve disk through the connection holes which secures the movable core to the leaf spring.

Abstract: A liquid sealed suspension unit includes a first member and a second member which are independent of each other and which are coupled together. A cylindrical rubber mount (43) is fastened to the first member, and the second member is mounted so as to be slidable in an axial direction thereof relative to the cylindrical rubber mount (43). The cylindrical rubber mount (43) has a plurality of rubber layers (46a, 46b, 46c) laminated via a plurality of cylindrical members (45a, 45b, 45c) such that they are different with respect to at least either of (i) thickness in their radial direction and (ii) height in their axial direction. A spring member (57), in the form of at least one spring coil, is interposed between a damper plate member (50) and an inner surface of a vessel (40) at the bottom of the vessel. This construction provides an increased displacement amplitude in the axial direction, and an excellent vibration absorptivity for both a roll and a pitch can be achieved.
