Abstract: The invention relates to a gear set of the type comprising a generally annularly shaped internally toothed ring member and an externally toothed star member having at least one fewer teeth than the ring member. The star member has an axis disposed eccentrically relative to the axis of the ring member. These parts are normally formed with low tolerances to facilitate fluid tight sealing between the meshing teeth. A different mode of sealing is provided which comprises sealing plates slidably disposed in radially extending slots formed in the ring member teeth.

Abstract: A bypass valve for use in a hydraulic system having a hydraulic motor or pump. The bypass valve shunts the motor or pump and connects the supply and discharge lines thereto and in response to pressure drops across the motor or pump bypasses fluid to keep the motor speed or pump output constant. The bypass valve compensates for motor or pump fluid leakage and keeps the sum of the quantity of fluid flow through the bypass valve and the leakage fluid constant. The bypass valve has a nonlinear characteristic curve determined by bypass orifices of varying dimensions controlled by a pressure-responsive axially movable slide.

Abstract: A hydraulic system in which the reversal of direction of a hydraulic motor therein is accomplished by a changeover control unit which comprises a four-way, changeover valve having changeover passages connecting the motor with a fluid pressure supply line and a discharge line. A restrictor provided for controlling flow in the discharge line is variably opened and closed in response to operation of the changeover valve. A metering valve in the control unit is responsive to pressure drops across the restrictor and operates to bypass supply fluid to the discharge line downstream of the restrictor to change over without damage to the system.
