klepopening

Klepopening is a Dutch term that literally means the opening of a valve. In various technical domains it is used to describe how open a valve is, which in turn governs flow, pressure, and system performance. The concept is generic rather than a fixed, field-specific term, and its exact meaning depends on the context.

In mechanical engineering and automotive contexts, klepopening refers to the degree to which an engine valve is lifted by the camshaft. The amount of lift and the duration of opening determine how much air and fuel can enter the cylinder and how exhaust is vented. Measurements are typically given as valve lift (in millimeters) and opening duration (in degrees of crankshaft rotation). These parameters are influenced by cam geometry, timing, and, in modern engines, variable valve timing systems.

In medicine, klepopening can describe the opening area of a heart valve as seen in imaging. A reduced opening, or stenosis, affects blood flow and may be evaluated by imaging modalities such as echocardiography, which assesses the effective orifice area and flow patterns to gauge severity and hemodynamic impact.

In hydraulic and pneumatic systems, klepopening denotes the cross-sectional area through which fluid can flow when a valve is actuated. It controls flow rate and pressure drop and is determined by valve design and the position of the actuator. Overall, klepopening is a descriptive term used across disciplines to denote how far a valve is open and the resulting effect on system behavior.
