Voltage regulator module - Wikipedia
A voltage regulator module (VRM), sometimes called processor power module (PPM), is a buck converter that provides microprocessor and chipset the appropriate supply voltage, converting +5 V or +12 V to a much lower voltage required by the CPU and chipset, allowing processors with different supply voltage to be mounted on the same motherboard. On personal computer (PC) …
How a Hydraulic Tensioner Works
A hydraulic tensioner system consists of a hydraulic actuator in combination with a tensioner pulley. The movement of the piston rod of the actuator is transmitted to the tensioner pulley via an integrated or separate lever (Figure 2). The hydraulic actuator works like a suspension strut, where a spring in combination with the damping feature ...
