Patent number: 9102414Abstract: Apparatuses and systems that use a variable displacement motor-pump (VDMP) to control the position and speed of a hose for an aerial refueling system are disclosed. At displacements greater than required to hold a position of the hose, the VDMP operates in a motor mode to retract the hose. For lesser displacements, the VDMP operates in a pump mode to control extension of the hose. In accordance with some embodiments, a pump-motor relief valve operates to throttle hydraulic fluid flow from the VDMP and to control mixing of hydraulic fluid flowing from the VDMP with system hydraulic fluid.Type: GrantFiled: August 28, 2012Date of Patent: August 11, 2015Assignee: Federal Industries, Inc.Inventors: Asher Bartov, Charles Kubilos

At VDMP displacements greater than required to hold a position of the hose, the VDMP operates in a motor mode to retract the hose. For lesser VDMP displacements, the VDMP operates in a pump mode to control extension of the hose. In accordance with some embodiments, a dual orifice conveys hydraulic fluid at varying rates depending upon the VDMP operational mode.Type: GrantFiled: August 28, 2012Date of Patent: August 11, 2015Assignee: Federal Industries, Inc.Inventor: Asher Bartov
