[Problem] To provide a solenoid-type variable damper that improves piston strength and prevents disconnection of the electromagnetic coil, and the like. [Solution] A piston (16) comprises a piston body (30), an expansion-side valve plate (41), a contraction-side valve plate (42), an electromagnetic coil (43), and a bolt (44). The piston body (30) is cast as a single piece and is manufactured through a powder metallurgy method, a die casting method, or the like, using a ferrite-based or other ferromagnetic material as a raw material, and comprises a cylindrical outer yoke (31) that is in slidable contact with the inner periphery of a cylinder (12); a columnar inner yoke (34), the outer periphery of which faces the inner periphery of the outer yoke (31) across first and second gaps (32, 33); and a connecting section (35) in the central part in the axial direction of the piston (16), which connects the outer yoke (31) and the inner yoke (34) and divides the first and second gaps (32, 33) from each other. The electromagnetic coil (43) is fit into the second gap (33) of the piston body (30).

A plunger seal (1) for a pump, which is used for a fuel injection pump for a direct-injection gasoline engine, in which, even if a resin material is used as a fuel seal member (12), the plunger seal can be made compact, sealing ability is increased, and assembling man-hours can be reduced, and in which set sealing performance can be achieved when a U-shaped elastic member (33) for applying an urging force is used in a groove (41) formed in the fuel seal member (12). The resin fuel seal member (12) and an oil seal member (13) are assembled to form one seal system. Further, when the U-shaped elastic member (33) is installed in the groove (41), the axial position (L1) of an end surface (44a) that is on the side opposite the side to be sealed and belongs to a flange (44) for fixation formed on the inner peripheral surface of the groove (41) is positioned more on the side (B) opposite the side to be sealed than the axial position (L2) of a head section (15b) of a seal lip (15) of the fuel seal member (12).

The invention relates to a device for the production of a reactive flowable mixture, including a mixing block (1) which includes at least one first passage (2) and second passage (4) for at least one first component (3) of the mixture and a collection passage (7) for the mixture (6). The first and second passages are communicated to the collection passage (7) which comprises at least one mixing mechanism (36).
