now the guy emptying with hydrodynamic adjustment continues the extent of fluid placed in the circuit operation.with or without internal system of direct coupling between the shaft and the shaft.

摘要

in a hydrodynamic coupling (1) of the type for emptying means for placing the fluid in the operating circuit in order to achieve step by step and precision the degree of fillinghole of the cavity (7) which depends on the speed of rotation of the tree out (60).preferably is used in a fuel pump (27) operated by an electric motor (124) whose rotation speed is varied by a frequency converter (122).the gasket may be equipped with a means (30) for coupling of the trees (50, 60), fixed internally to the coupling, commanded by a pump (29) inserted into a separate circuit.it is also provided the use of a microprocessor (d) to automate the operation of the time (fig. 3).
