摘要： An adjustment safeguard for a set screw that is rotatably held in a housing has a cap that is non-rotatably secured on the head of the set screw. The cap is received in a sleeve of the housing and surrounded with minimal radial play by the sleeve that is essentially coaxially positioned relative to the cap. The cap is received with its axial length in the sleeve. The cap has a projection and the sleeve has a stop arranged in the interior of the sleeve. Projection and stop interact with each other in a rotational direction of the set screw. The cap has a top part and a separate bottom part. The bottom part is secured axially and non-rotatably on the head of the set screw. The bottom part engages with form fit the top part in the rotational direction and is axially connected to the top part.

摘要： A two-stroke engine (1) has a combustion chamber (3) disposed in a cylinder (2). The combustion chamber (3) is delimited by a reciprocating piston (5). The piston (5) drives a crankshaft (7) via a connecting rod (6) and the crankshaft (7) is rotatably journalled in a crankcase (4). The two-stroke engine (1) has an intake channel (8) for the supply of fuel into the crankcase (4), an outlet (13) for exhaust gases from the combustion chamber (3) and an air channel (10) for the supply of substantially fuel-free air. A throttle element (18) is mounted in the air channel (10). At pregiven positions of the piston (5), the crankcase (4) is connected via at least one transfer channel (14) to the combustion chamber (3). In order to prevent air from being drawn by suction into the air channel because of leakages during idle or at low rpm, a fluid connection is provided between the air channel (10) downstream of the throttle element (18) and the crankcase (4) for underpressure compensation which connection is present at least partially for a position of the piston from 90° ahead of bottom dead center to 90° after bottom dead center. A connection between the crankcase (4) and the intake channel (8) can be provided in lieu of, or in addition to, the connection to the air channel (10).
