Fixed/rotating mechanical assembly for forming e.g. pump, has mechanical system with set of pinions driven by another set of pinions to rotate piston for controlling operating cycle of piston, where system organizes kinematics of assembly

摘要

The assembly has central axle (8) for carrying out a relative movement between a fixed or rotary cylinder (9) and a piston (11), where the axle is connected to an output shaft (45) of a case (1). The axle has a mechanical system (15) with a set of pinions (37, 38) driven by another set of pinions (22, 23) to rotate a piston (11) for controlling operating cycle of the piston in the cylinder, where the system organizes kinematics of the assembly.
