WebA lever is a rigid arm that is braced against a turning point, or fulcrum. Pushing at one end of the arm creates a larger force at the other end. Levers are important parts in many tools, from hammers and crowbars to see-saws, bicycle pedals, nutcrackers, and tweezers. Science. Simple machines. WebSpring Piston machines have a calibrated spring that forces water through the grounds for you. When you pull the lever down, you compress the spring. When you release the lever, the spring applies the pressure to the grouphead and pulls the shot. Direct Lever machines don’t have this spring.

The lever is a movable bar that pivots on a fulcrum attached to a fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. As the lever rotates around the fulcrum, points farther from this pivot move faster than points closer to the pivot. Therefore, a force applied to a point farther from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity.
