The output quantity of liquid due to such relative motion is defined by the geometric construction.Type: ApplicationFiled: October 12, 2017Publication date: April 18, 2019Applicant: Zhejiang FAI Electronics Co., Ltd.Inventors: Daguang XI, Ping ZHANG, Qijiang LE, Luming XU, Yanxiang YANG

Publication number: 20190113031Abstract: The unload circuit includes a pump oil passage that connects between a hydraulic pump and a direction control valve, a tank oil passage that connects between the direction control valve and a hydraulic tank, a pressure compensating flow control valve interposed between the pump oil passage and the tank oil passage, a pilot operated relief valve interposed between the pump oil passage and the tank oil passage, and an unloading solenoid valve interposed in a vent oil passage of the pilot operated relief valve. The failure diagnosis device includes a pressure sensor that measures a pressure of the pump oil passage, and a controller that receives a pressure signal from the pressure sensor. The controller performs failure diagnosis of the unload circuit based on a differential pressure between a first pump oil passage pressure during unloading and a second pump oil passage pressure during on-loading.Type: ApplicationFiled: March 24, 2017Publication date: April 18, 2019Applicant: TADANO LTD.Inventors: Naoto KAWABUCHI, Naofumi YOSHIDA, Yasuhiro FUKUMORI

Publication number: 20190113034Abstract: An electric refrigerant drive, in particular a refrigerant compressor for an air conditioner of a motor vehicle, has an electric motor drive module and a compressor module coupled to the drive module. The drive module has a motor housing which houses an electric motor with a rotatable motor shaft and is joined to an end shield. The drive module also comprises a fluid-tight housing partition opposite the end shield, thereby forming an electronic housing that receives an electronic motor unit and is closed by a housing cover. The compressor module has a compressor housing which is attached to the end shield of the motor housing of the drive module and which receives a compressor part that is coupled or can be coupled to the drive module so as to be driven.Type: ApplicationFiled: December 15, 2016Publication date: April 18, 2019Inventor: MARCUS PODACK

Publication number: 20190113035Abstract: The present teachings include an energy recovery device usable in multiple applications, for example hydropower and vehicle power plant applications. In one aspect, an energy recovery device includes a housing having an inlet and an outlet in fluid communication with an internal cavity, and a pair of counter-rotating rotors having intermeshed lobes disposed within the housing internal cavity. Each rotor defines a transport volume between the housing and a pair of adjacent lobes and has a calculated maximum ideal twist angle below which the transport volume will be sealed from both the housing inlet and housing outlet. Each rotor also has an actual twist angle that exceeds the maximum ideal twist angle.Type: ApplicationFiled: March 9, 2017Publication date: April 18, 2019Inventors: Matthew Gareld SWARTZLANDER, David YEE
