  • Publication number: 20210088130
    Abstract: A hydraulic circuit for moving a fluid includes an electric pump, a primary circuit, and a secondary circuit. The hydraulic circuit also includes a controller and a hydraulic control module. The hydraulic control module includes a solenoid valve assembly. Moreover, the controller is configured to control a pressure of the fluid at the output of the solenoid valve assembly. Finally, the hydraulic control module includes a switch valve assembly configured to selectively route the fluid from the pump to the primary circuit when the pressure of the fluid at the output of the solenoid valve assembly is lower than a predetermined pressure and to selectively route the fluid to the secondary circuit when the pressure of the fluid at the output of the solenoid valve assembly is greater than the predetermined pressure.

  • Publication number: 20100119396
    Abstract: The present invention is a variable displacement pump having an inner rotor rotatable about a first axis and having at least two slots. The pump also has at least two vanes, each located in a distinct one of the at least two slots. The pump also has an outer rotor rotatable about a second axis, operably associated with the inner rotor, the outer rotor having two or more recesses, each configured to receive one of the vanes. The pump also includes an expandable chamber formed by the outer rotor and the inner rotor, an eccentric ring surrounding the outer rotor, and a housing. The eccentric ring is located within the housing for adjusting the relative relationship between the first axis and the second axis in order to vary the displacement of the pump.
