Performance study of a diaphragm type crankcase pressure control valve
Pressure control valve (PCV) is implemented in internal combustion engine to regulate crankcase pressure. In this study, the performance of a diaphragm PCV valve is investigated numerically and experimentally. Firstly, numerical simulation is carried out using commercial code to predict the flow and pressure distribution inside the valve. Furthermore, downstream and upstream pressure of the val...
متن کاملTheoretical and Experimental Analysis of a Coupled System Proportional Control Valve and Hydraulic Cylinder
The aim of this paper is to analyze the driving system actuated by a proportional directional control valve on a hydraulic cylinder. In order to evaluate the dynamic interaction between the proportional valve and the cylinder theoretical analysis, numerical simulations as well as experimental test are performed. Coupling cylinder and proportional valve, it is very important to know the ratio of...

15 صفحه اولA Study of the Mechanism and Characteristics of a Pwm-based Valve Control System with No Throttle Loss
For the problem of low efficiency of conventional valve control systems, an economical PWM-based valve control system with no throttle loss is put forward and examined in this paper. There are four no-throttling-loss units used to control a single rod cylinder in this fixed displacement pump system, which breaks the mechanical linkage of meter-in and meter-out flow in the traditional four way d...
