When the suction tube is coupled to the container and the pliable sealing ring is sealingly engaged with the interior wall of the container, actuating the actuator mechanism can cause the viscous fluid to be suctioned upwardly through the suction tube and output from the output port, ambient air to be drawn into the container, and the pliable sealing ring to move downwardly.Type: ApplicationFiled: October 29, 2018Publication date: May 2, 2019Applicant: Newer Commuter, LLCInventor: Andrew C.

Publication number: 20190128263Abstract: A scroll compressor can include a housing, a rod member, and a nut. The housing can define a first bore. The non-orbiting scroll can include a flange. The flange can define a second bore. The rod member can have a first axial end that is coupled to the housing. The rod member can extend from the first bore and through the second bore to a second axial end of the rod member. The rod member can include at least one set of external threads. The at least one set of external threads can be disposed about the second axial end of the rod member. The nut can be threadably engaged with the second axial end of the rod member. The second bore can be disposed axially between the nut and the housing. The primary forces acting within the rod member are tensile forces, while torsional shear forces are minimized.Type: ApplicationFiled: October 29, 2018Publication date: May 2, 2019Applicant: Emerson Climate Technologies, Inc.Inventors: Bryan James PENKAL, Calvin W.

Publication number: 20190128264Abstract: The objective of the present invention is to reduce loss factors that occur inside an oil-cooled screw compressor and to improve energy efficiency. In oil-cooled screw compressors, compression is carried out by reducing the volume of an operation chamber in which a gas to be compressed and an oil are mixed and contained, and when a predetermined rise in pressure is complete, a discharge port opens and the gas to be compressed and the oil are discharged. In the operation chamber, the reduction in volume continues and reaches zero, such that the operation chamber disappears, and the opening area of the discharge port also gradually decreases. Immediately before the operation chamber disappears, the ratio of the oil within the operation chamber is high and the opening area of the discharge port is small. Therefore, the discharge resistance increases and the internal pressure dramatically rises, and this has led to increases in the torque rotating the rotor.Type: ApplicationFiled: March 30, 2017Publication date: May 2, 2019Inventors: Hirotaka KAMEYA, Hideharu TANAKA, Masahiko TAKANO, Takeshi TSUCHIYA
