Abstract: A fully variable valve train with a rotary plunger for an internal combustion engine. A motor actuates a high-pressure oil injection pump; when a timing driven electromagnetic valve connected to an oil inlet is opened, high-pressure oil enters a hydraulic cylinder; and when the force applied to a plunger by the hydraulic oil is larger than the force of a valve returning spring, the plunger is pushed to move down, so that a valve is opened. When the valve is required to be return, the timing driven electromagnetic valve connected to the oil inlet is closed, and the timing driven electromagnetic valve connected to the oil inlet is opened; the valve moves up under the action of the valve spring, pushing the plunger to move up and thereby discharging the low-pressure oil out of the hydraulic cylinder, then the plunger and the valve return to the initial positions.

Abstract: A method for establishing a geometrical imperfection database of aerospace thin-walled structures is disclosed. The method comprises the following steps: 1) design the shell quality inspection card that is suitable and convenient to measure the geometrical imperfections for field workers. Obtain the parameters and geometrical imperfections of shells by filling data of measurement points in the shell quality inspection card; 2) perform characteristics combing, mathematical description and component analysis for the geometrical imperfections obtained in the first step; 3) collect and analyze the geometrical imperfection information of multiple aerospace thin-walled shells and establish the geometrical imperfection database based on the first step and second step. The method will effectively serve the development of aerospace equipment, shorten the design cycle and provide guidance and specifications for the design of the thin-walled components carrying main load.

Abstract: An electrical connector includes an insulative housing having a base and a tongue, an upper and lower rows of contacts mounted in the insulative housing and exposed upon the tongue and a pair of grounding pieces separated from each other and retained in the insulative housing between the two rows of contacts. Each grounding piece includes a securing portion disposed in the mating tongue and defines an abutment exposed upon corresponding side face of the mating tongue. The pair of grounding pieces are far away from corresponding power contacts along the transverse direction thereby resulting that the grounding pieces are wholly offset from the power contacts in the vertical direction so as to avoid the power contacts from electrical sparkle.
