Priority Valve And Method For Using Same
US Patent:
4913181, Apr 3, 1990
Filed:
Mar 8, 1988
Appl. No.:
7/165708
Inventors:
Jerome A. Mortenson - Rockford IL
Assignee:
Sundstrand Corporation - Rockford IL
International Classification:
G05D 1102
US Classification:
137 12
Abstract:
A priority valve (10) useful in, for example, an aircraft constant speed drive system controls sump oil level and prioritizes oil flow to several critical components during periods of oil supply interruption. The priority valve (10) includes a movable spool (17) which has a reduced portion (19) surrounded by a spring (18) to urge the spool (17) toward a closing position in which oil is supplied directly from an accumulator (80) to a deaerator (20). The spool (17) is caused to move against the bias of the spring (18) by output oil pressure of the deaerator (20) which is input into the valve (10). The member (17) has an axial passageway (101) with branch radial passageways (103, 104, 105, and 106) for selectively prioritizing the flow of oil to critical system components such as a generator rotor (52), a generator stator (53), and a hydraulic case (90) so that whatever oil is available in the system is made available to the most critical system components.
Process And Apparatus For Filling A Constant Speed Drive
US Patent:
4895192, Jan 23, 1990
Filed:
Dec 24, 1987
Appl. No.:
7/137579
Inventors:
Jerome A. Mortenson - Rockford IL
Assignee:
Sundstrand Corporation - Rockford IL
International Classification:
B65B 3102
US Classification:
141 5
Abstract:
A service valve (10) is provided to provide an apparatus and method for filling a constant speed drive without overfilling and for preventing gas entrapment in the oil circuit of the drive. The valve (10) has a spool (12) movable in response to pressure from a filling fluid so as to connect the filling fluid with the drive circuit until a predetermined level has been reached at which point a signal is generated to allow the operator to remove the source of filling fluid. An air vent float valve (44) and a pressure switch (28) in the oil circuit allow the trapped gas to be vented from the oil circuit.
