Abstract
The hydrostatic drive with regeneration circuit comprises a geroter flow divider which operates in conjunction with a two position three way valve and a check valve to provide regeneration flow for the hydrostatic drive when the valve is energized.
Claims11
A closed loop hydrostatic drive with regeneration circuit comprising:
- a) a first pump which draws fluid from a lower pressure line and supplies a higher pressure line,
- b) a charge pump with,
- c) at least one one-way check valve in a supply line between said charge pump and said first pump,
- d) at least one hydraulic motor having an inlet and an outlet,
- e) a valve means in fluid communication with the outlet of said at least one hydraulic motor and
- d) a rotary flow divider
- wherein said first pump supplies fluid to the at least one hydraulic motor,
- wherein exhaust flow from the at least one hydraulic motor can be diverted to the rotary flow divider by said valve means,
- wherein a portion of the flow from the rotary flow divider is returned at low pressure to said lower pressure line of said closed loop hydrostatic drive, and
- wherein a portion of the flow through the rotary flow divider is supplied to said higher pressure line resulting in a volume of flow into said at least one hydraulic motor that is greater than the volume supplied by said first pump.
