Abstract: A bent axis pump wherein the coupling between a cylinder body and a connecting pin of a back body takes place by the interposition of a bush suitable for guiding the rotation of the cylinder body limiting the friction between the cylinder body and the pin. The pin life is considerably extended.

Abstract: A device for engaging power takeoffs, primarily used to drive a load from the engine of a vehicle, has an electromagnet with a single winding of small size which is driven by a microprocessor system in PWM mode allowing to differentiate the current intensity of the engaging phase and of the phase of maintaining said engaging. The control system monitors, without the aid of external sensors, parameters such as electromagnet current, power supply and electromagnet voltage, electromagnet winding resistance, electromagnet winding inductance. From these parameters, the system is able to determine the engaging or unengaging position of the power takeoff, and it is able automatically to uncouple if the monitored parameters do not fall within the expected ranges, simultaneously notifying the user of the protective intervention.
