Patent number: 11971088Abstract: A linear actuator includes a planetary gear system includes a sun gear, a ring gear, and a planet carrier. A linear output mechanism is coupled to the planetary gear system. A first motor is configured to drive a first input shaft, and the first input shaft is coupled to the planet carrier. A second motor is configured to drive a second input shaft, and the second input shaft is coupled to the ring gear. A first brake is coupled to the first motor and is configured to be engaged into a braked position that holds the planet carrier fixed. In the braked position, rotation of the ring gear results in rotation of the sun gear for linear displacement of the linear output mechanism.Type: GrantFiled: January 20, 2021Date of Patent: April 30, 2024Assignee: HAMILTON SUNDSTRAND CORPORATIONInventor: Floyd Richard Emmons

Patent number: 9617922Abstract: A jet engine actuation system includes a first ring gearbox, a second ring gearbox and an actuator. The first ring gearbox includes a first ring driveshaft coupled to a first portion of a synchronization ring included in a jet engine. The second ring gear box includes a second ring drive shaft coupled to a second portion of the synchronization ring. The actuator has a first actuator gearbox configured to generate a first rotational output and a second actuator gearbox configured to generate a second rotational output. A first drive shaft transfers the first rotational output to the first ring gearbox and a second drive shaft transfers the second rotational output to the second ring gearbox. The actuator simultaneously controls the first and second actuator gearboxes such that the first and second rotational outputs are simultaneously transferred to the first and second ring gearboxes to rotate the synchronization ring.Type: GrantFiled: March 27, 2014Date of Patent: April 11, 2017Assignee: HAMILTON SUNDSTRAND CORPORATIONInventor: Floyd Richard Emmons

Patent number: 9399953Abstract: A pump sharing valve for a gas turbine engine fuel system includes a housing having multiple ports. A sleeve is arranged in the housing and includes an inlet window and first, second and third windows axially spaced apart from one another. A spool is slidably received in the sleeve and includes a diameter and first and second cylindrical portions. The first cylindrical portion selectively connects the inlet window to the second and third windows. The second cylindrical portion selectively connects the inlet window to the first window. The spool is movable between first and second positions relative to the first, second and third windows to regulate flow. The first and second cylindrical portions respectively includes first and second widths. A first ratio corresponds to the first width to the spool diameter and a second ratio corresponds to the second width to the spool diameters. The first ratio is between 1.83 and 1.93 and the second ratio is between 1.22 and 1.32.Type: GrantFiled: September 19, 2012Date of Patent: July 26, 2016Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Peter M.

Patent number: 8127786Abstract: A selector valve selects between the supply of a primary pressure supply and a secondary pressure supply to a downstream use. The selector valve moves between a first position at which it supplies fluid from a primary line to the use, and a second position at which it supplies fluid only from a secondary line to the use. The selector valves moves through an intermediate position at which fluid is supplied from both supplies to the use.Type: GrantFiled: April 3, 2008Date of Patent: March 6, 2012Assignee: Hamilton Sundstrand CorporationInventor: Floyd Richard Emmons
