Date Sep. 29, 1994The relay has a base (1) with stationary mating contact elements (11, 12, 13, 14), a coil (5), a permanent magnet (4) and also a rocker armature (3) which is arranged between the coil and the base, is connected to movable contact elements (21, 22, 23, 24) and is mounted on the base by means of bearing strips, the bearing strips simultaneously serving as electrical connections for the movable contact elements. The bearing strips (25, 26) are secured to the bearing supports (15, 16), which are designed as connection elements, of the base in planes extending at right angles to the basic plane of the base. As a result, the contact separation can be set with low tolerance even during production, and it is not dependent on tolerances of the individual parts. This structure consequently permits non-problematic, cost-effective production of the individual parts and accurate assembly without the requirement of subsequent adjustment.

Abstract: The invented internal combustion engine comprises a first cylinder (12) and a second cylinder (14), whereby the first cylinder (12) working volume is greater than that of the second cylinder (14) that is performed in the first cylinder (12) head. A first piston (16) moves in the first cylinder (12) and a second piston (18) moves in the second cylinder (14), whereby the second piston (18) is performed as a projection on the first piston (16) head. The first cylinder (12) has an air inlet (25) and an exhaust port (27), and a first fuel source (34) ensures fuel for the second cylinder (14). The second piston (18) head (35) is situated at a certain distance from first piston (16) head (36) and connected therewith. Said first piston (16) head (36) has an edge (37), whose dimension in axial direction is relatively small if compared with the distance of the first piston (16) head (36) from the second piston (18) head (35) in axial direction, too. If the pistons are in their top dead center position a combustion space (20) is thus defined between the first piston (16) head (36), the second piston (18) head (35) and the second cylinder (14) wall (14a). During a portion of a power stroke the combustion space (20) is connected with both the cylinders (12, 14).
