<p>Piston position detector for generating an electrical signal varying linearly with piston travel of a piston machine. The device comprises a metal cylinder (6) rotating about an eccentric axis (7) synchronously with the crankshaft of the piston machine, the ratio of eccentricity (9) to cylinder radius being substantially equal to the ratio of crank length to connecting rod length of the piston machine. The cylinder surface is faced by the probe (10) of an eddy-current distance meter, the arrangement being such that the desired linear relation is obtained.</p> |
