Abstract
A governor is disclosed in which dust which may comprise steel powder, fine particles of sand and so on will be removed from a hydraulic working fluid by subjecting the working fluid to centrifugal force. A fluid passage for the working fluid is formed in a housing of the governor and a chamber communicates with the passage at the opening. The fluid passage has an opening located such that dust contained in working fluid will enter into the chamber through the opening while the housing is rotating. Within the chamber working fluid will be stagnant and dust sedimented.
