Patent number: 9677578Abstract: A fluid flow control device includes a body having an inlet connection, an outlet connection, and a discharge port. A supply path extends between the inlet connection and the outlet connection and a booster module is disposed within the body. The booster module includes a control element and an actuator element and defines an exhaust path extending between the outlet connection and the discharge port. A supply port is disposed within the booster module along the supply path between the inlet connection and the outlet connection.Type: GrantFiled: September 19, 2013Date of Patent: June 13, 2017Assignee: FISHER CONTROLS INTERNATIONAL LLCInventors: Michel K. Lovell, Ryan J. Jwanouskos, Gary L. Scott, Kenneth W. Junk

Patent number: 9074695Abstract: A volume booster for an actuator system advantageously includes an adjustable restrictor, such that the exhaust capacity of the device can be adjusted for specific applications. The device comprises a body, a supply path, an exhaust path, and the restrictor. The supply path operates to provide a supply of fluid to boost a stroke time of an actuator in the actuator system, e.g., in an opening direction. The exhaust path operates to accommodate backpressure relief when the actuator system operates the actuator in a closing direction, for example. The restrictor is disposed within the exhaust path and is selectively manipulable between a plurality of positions to define a plurality of distinct exhaust capacities, thereby eliminating any requirement to change the entire volume booster to achieve a different exhaust capacity.Type: GrantFiled: August 15, 2011Date of Patent: July 7, 2015Assignee: FISHER CONTROLS INTERNATIONAL LLCInventors: Michel K. Lovell, Kenneth W. Junk, Ryan J. Jwanouskos

Patent number: 9032986Abstract: A volume booster for a fluid flow control device comprises a supply path for supplying a fluid boost to facilitate actuation of an actuator in a first direction, and an exhaust path for enabling controlled exhaust to facilitate actuation of the actuator in a second direction. The supply path defines a supply resistance that is set by the geometry of a supply trim component. The exhaust path includes an exhaust resistance that is set by the geometry of an exhaust trim component. The supply and exhaust trim components are independently removable and replaceable with replacement components to customize the exhaust and supply resistances, and therefore, the exhaust and supply capacities for specific applications.Type: GrantFiled: August 12, 2011Date of Patent: May 19, 2015Assignee: FISHER CONTROLS INTERNATIONAL LLCInventors: Michel K. Lovell, Kenneth W. Junk, Ryan J. Jwanouskos

Patent number: 8917066Abstract: A system for managing shunt utilization among multiple power converters sharing a common DC bus is disclosed. Each power converter includes a shunt device, typically one or more power resistors, configured to dissipate power from the DC bus. The power converter is configured according to an initial set of configuration parameters to selectively connect the shunt device to the DC bus. Each power converter monitors the amount of power being dissipated from the DC bus via the shunt device connected to that power converter and determines a utilization rate for the shunt device. As the utilization rate increases, the configuration parameters are modified to less frequently connect the shunt device to the DC bus. As the utilization rate decreases, the configuration parameters are modified to more frequently connect the shunt device to the DC bus.Type: GrantFiled: August 8, 2012Date of Patent: December 23, 2014Assignee: Rockwell Automation Technologies, Inc.Inventors: Gerry M. Nagel, Ryan J. Jwanouskos

Publication number: 20140026746Abstract: A fluid flow control device includes a body having an inlet connection, an outlet connection, and a discharge port. A supply path extends between the inlet connection and the outlet connection and a booster module is disposed within the body. The booster module includes a control element and an actuator element and defines an exhaust path extending between the outlet connection and the discharge port. A supply port is disposed within the booster module along the supply path between the inlet connection and the outlet connection and at least a first damping means operatively connected to the booster module.Type: ApplicationFiled: September 19, 2013Publication date: January 30, 2014Applicant: FISHER CONTROLS INTERNATIONAL LLCInventors: Michel K.
