Abstract
A machine, such as an engine, which includes a cylinder (1), an essentially cylindrical piston (5) set on bearings and equipped with an eccentrically-set shaft (11), an inlet port or valve (8), an outlet port or valve (9), and a lever device (7), which is attached by bearings to a shaft (6) and which is intended to be in essentially tight contact with the piston (5). The cylinder (1) forms an essentially cylindrical chamber for the rotary piston (5) and a partially cylindrical chamber for the lever device (7) that moves backwards and forwards. The piston (5) is equipped, in the interior of the working chamber, with sliding-ring-type bearings (13, 14).
Claims15
A machine, such as an engine or pump, which inclues a cylinder (1), a piston (5) equipped with an eccentrically set shaft (11) set in bearing in the cylinder block, an operating-medium inlet port or valve (8), an outlet port or valve (9), and a lever device (7), which is mounted in bearings on shaft (6) and which is intended to be in essentially tight contact with the piston (5), so that the cylinder (1) forms an essentially cylindrical chamber for the rotary piston (5) and a partially cylindrical chamber for the lever device (7) that moves backwards and forwards, characterized in that the lever device (7) is mounted in bearings at one end of a shaft (6) which is essentially parallel to the shaft (11) and that the lever device (7) is intended to be in essentially tight contact with the surface of the piston (5) at the opposite end or near to it.
