Patent number: 11971038Abstract: A single-stage enthalpy enhancing rotary compressor and an air conditioner having same. The single-stage enthalpy enhancing rotary compressor includes: at least one single-stage cylinder, a rotator, an upper flange, and a lower flange. The rotator is arranged inside the cylinder and is rotatable, a compression chamber is formed between the rotator and an inner peripheral wall of the cylinder, a vapor injection opening is defined in at least one of the upper flange the lower flange, and the vapor injection opening is configured to supply gas outside the compressor to the compression chamber directly. According to the present disclosure, two-stage compression is realized without adding an extra cylinder, thereby effectively enhancing a circulation of refrigerant, improving cooling performance of the air conditioner under high environmental temperatures.Type: GrantFiled: September 26, 2022Date of Patent: April 30, 2024Assignee: GREE ELECTRIC APPLIANCES, INC. OF ZHUHAIInventors: Guanghui Xia, Xiaocheng Lai, Shuo Xiong, Junchu Liang, Boming Zhu, Lihui Zhang, Wei Zhu, Xuechao Ding, Fuqiang Zhang, Hao Mei

Patent number: 9302722Abstract: A seal assembly can be incorporated into a track pin joint assembly including a pin defining a longitudinal axis, a first member and a second member both coaxial with the pin about the longitudinal axis. The first member is pivotable about the longitudinal axis with respect to the second member and includes a load ring engagement surface defining, at least in part, an axially-extending seal cavity disposed in proximal relationship to the second member. A seal assembly including a seal ring and a load ring is disposed in the seal cavity and sealingly engages the first member and the second member. The load ring includes a main body and a neck having a neck perimeter with a first sealing blade disposed along the neck perimeter and comprising an outwardly-extending projection. The first sealing blade is adapted to sealingly engage one of the seal ring and the first member.Type: GrantFiled: July 31, 2014Date of Patent: April 5, 2016Assignee: Caterpillar Inc.Inventors: Guanghui Liang, Mark Diekevers, Mark Kiesel, Darren Antoine, Temitope Akinlua, Travis King

Patent number: 8985590Abstract: A seal assembly can be incorporated into a track pin cartridge assembly of an undercarriage of a track-type machine. The seal assembly can include a pin defining a longitudinal axis and first and second members both coaxial with the pin about the longitudinal axis. The first member is pivotable about the longitudinal axis with respect to the second member and includes a load ring engagement surface defining a seal cavity disposed in proximal relationship to the second member. A seal assembly, including a seal ring and a load ring, is disposed in the seal cavity and sealingly engages the first and second members. A radial segment of a first member engagement surface of the load ring is radially offset, measured along a radial axis perpendicular to the longitudinal axis, from a radial segment of a seal ring engagement surface of the load ring.Type: GrantFiled: April 19, 2012Date of Patent: March 24, 2015Assignee: CaterpillarInventors: Guanghui Liang, Mark Diekevers, Mark Kiesel, Eric Johannsen, Jason Sebright

Publication number: 20120161510Abstract: A seal assembly includes a first member that pivots about an axis of a joint relative to a second member. The seal assembly includes adhesive, a seal ring and a load ring for a seal cavity of the first member. The adhesive may be applied between at least one of the seal cavity and a first end face, the seal cavity and a first surface, the seal ring and an annular inner peripheral surface, the seal ring and a second surface, and the seal ring and a second end face. Alternatively, the seal cavity may comprise a roughened area where the load ring contacts the seal cavity.Type: ApplicationFiled: December 7, 2011Publication date: June 28, 2012Applicant: Caterpillar Inc.Inventors: Mark S.
