enkelactie
Enkelactie refers to a type of valve or mechanism that operates in only one direction. This means it requires external force to return to its original position after activation. In hydraulic or pneumatic systems, an enkelactie cylinder, for example, is powered by fluid pressure in one direction only. The return stroke is then typically achieved by a spring, gravity, or the weight of the load. This design simplifies the control mechanism compared to double-acting systems where fluid pressure is used for both extending and retracting the actuator. Enkelactie systems are often chosen for applications where simplicity, cost-effectiveness, or fail-safe operation is prioritized. They are common in various industrial machinery, automotive components like hydraulic jacks, and even in simpler mechanical devices. The defining characteristic is the single-direction powered movement, with a passive or assisted return.
