Flow-Force Analysis in a Hydraulic Sliding-Spool Valve
Original scientific paper The necessary forces for the control of a hydraulic sliding-spool valve are normally determined by the stationary axial momentum forces of the oil flow through a valve. These forces increase with an increase in the volume flow and the pressure difference. Because of the limited actuating-force potential of normal electromechanical actuators, the direct actuation of con...
متن کاملSimulation of the cavitating flow in a model oil hydraulic spool valve using different model approaches
The contribution compares results of Large Eddy Simulations of the cavitating flow in a model oil hydraulic spool valve using an Euler-Euler and a one-way coupled EulerLagrange model. The impact of the choice of the empirical constants in the Kunz cavitation model is demonstrated. Provided these are chosen appropriately the approach can yield reasonable agreement with the corresponding experime...
متن کاملEffect of resin coating on adhesion of composite crown restoration.
The purpose of this study was to evaluate the effect of a resin coating technique on the microtensile bond strength (microTBS) of resin cement to dentin in composite crown restorations. Crown preparations were done on human molars. A resin coating material, Hybrid Bond, was immediately applied to the prepared dentin and light-cured, while the tooth without resin coating acted as the control. An...

متن کاملNoise Characteristics in Spool Valve with V-notches
Experimental investigations on the noise characteristics in spool valve with v-notches are conducted in this paper. Cavitation noise with frequency peak forms when the flow state changes form single phase turbulent to cavitating. The peak frequency decreases with the increase of the flowrate. On the other hand, jet flow develops intensely from the notches. Self-sustained flow oscillation produc...
