Abstract

The hydraulic piston motor comprising means for measuring the speed of rotation according to the invention comprises a rotating hydraulic distributor adapted to supply hydraulic pressure fluid in cycles to the pistons driving the motor, and having a revolving internal member (15) rotating integrally with the drive shaft (16) and comprising ducts (17) for distributing hydraulic fluid, a sensor (8) being present in a fixed position on the hydraulic distributor and facing the revolving member (15), the outer surface of which is formed with discontinuities (12) detectable by the sensor (8) which, corresponding to the periodic detection of the aforementioned discontinuties during the rotation of the revolving member (15), generates a signal at a frequency proportional to the speed of rotation of the member (15), means being present for protecting the sensors from the pressure of the hydraulic fluid in the fixed outer casing of the distributor.
