Patent number: 10087936Abstract: A compressor may include first and second scrolls, a seal assembly and a valve ring. The first scroll may include a first end plate having a discharge passage, a modulation port, and a biasing passage. The modulation port may be in communication with a first pocket formed between spiral wraps of the first and second scrolls. The biasing passage may be in communication with a second pocket formed between spiral wraps of the first and second scrolls. The modulation valve ring is axially displaceable relative to the seal assembly and the first scroll between first and second positions. The valve ring may abut an end plate of the first scroll and close the modulation port when in the first position. The valve ring may abut an axially-facing surface of the seal assembly and is spaced apart from the end plate to open the modulation port when in the second position.Type: GrantFiled: July 11, 2017Date of Patent: October 2, 2018Assignee: Emerson Climate Technologies, Inc.Inventors: Dennis D. Pax, Stephen Barry Tummino, Troy R. Brostrom, Anthony Joseph Dahlinghaus, Brian R. Butler

Patent number: 9784274Abstract: A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.Type: GrantFiled: May 13, 2016Date of Patent: October 10, 2017Assignee: Emerson Climate Technologies, Inc.Inventors: Troy R. Brostrom, Mark Hiszem, Richard A. Miu, Jason M. Warner

Patent number: 6709247Abstract: A compressor is driven by a drive shaft rotatably supported by a main bearing housing and a lower bearing housing. The main bearing housing positions a main bearing at or near a nodal point of the drive shaft during vibration by the drive shaft. The main bearing housing is designed such that the main bearing pivots during the vibration of the drive shaft in order to maintain surface contact between the bearing and the drive shaft to eliminate edge loading of the bearing.Type: GrantFiled: December 16, 2002Date of Patent: March 23, 2004Assignee: Copeland CorporationInventors: Harry B. Clendenin, Keith J. Reinhart, Wei Hain Sun, Troy R. Brostrom, Macinissa Mezache, Tom R. Hodapp
