Patent number: 11560980Abstract: A grease pumping device includes a pump body, a driving mechanism, a plunger pair, a reversing valve and a lever mechanism. A switching action between each valve position of a valve core of the reversing valve is driven by the lever mechanism. An output rotating shaft drives a toggle member rotating therewith, and when the output rotating shaft rotates reciprocally in forward and reverse directions, the toggle member toggles the lever mechanism in the forward and reverse directions, such that the lever mechanism swings reciprocally. At least one of the lever mechanism and the toggle member is an elastic structure, when the output rotating shaft rotates, the toggle member contacts the lever mechanism and drives the valve core to operate, when the valve core is switched to a corresponding valve position, the toggle member and the lever mechanism slide relatively by elastic deformation of the elastic structure.Type: GrantFiled: April 24, 2020Date of Patent: January 24, 2023Assignee: ZHENGZHOU AUTOL TECHNOLOGY CO., LTD.Inventors: Daping Zhao, Xingong Liu, Zhang Liu, Lifeng Ma

Patent number: 9593805Abstract: A liquid distributing valve includes a housing, an oil supply passage, an oil storage valve and a two-position three-way valve. The oil storage valve is separated into an oil storage chamber and an oil pressing chamber by a piston, and the oil storage chamber is in communication with an oil discharge port and has a spring pressing against the piston. The two-position three-way valve includes a valve body cavity having an oil inlet in communication with the oil supply passage, a valve core and a valve seat having a core hole in communication with the oil storage chamber via a bypass oil passage. When the valve core is at one position, the oil inlet is blocked off, and the oil pressing chamber is in communication with the oil storage chamber. When the valve core is at another position, the core hole is blocked off, lubricant enters the oil inlet.Type: GrantFiled: July 22, 2013Date of Patent: March 14, 2017Assignee: AUTOL TECHNOLOGY CO., LTDInventors: Daping Zhao, Jianhua Li, Yankai Si, Lifeng Ma
