Abstract

Apparatus for determining the operating parameters of a variable-volume hydraulic engine comprising a plurality of propulsion members (10) oscillating about a respective centre of oscillation (Cn) and a spherical body (6) associated with the driving shaft (7) and movable eccentrically (E) with respect to the centre of rotation (O) of the latter, and comprising at least two devices (50;150) each of which is respectively arranged on an associated propulsion member (10) and is designed to detect a parameter able to allow determination of the position of the point of eccentricity (E) of the driving shaft (7) with respect to the centre of rotation (O) of the driving shaft and the centres of oscillation (C1,C2) of said propulsion members (10), and a data processing unit (1000) able to store the data detected and perform the necessary calculation.
