Key circuits shown include parallel motors to develop The Basics Of Hydraulic Circuitry. The electric circuit (left) and hydraulic analogue (right). 4) Our computers contain millions of tiny series and parallel circuits working together to keep it functioning. 4: Filtration and Conditioning 3. The circuit carries current only if all switches are closed (On). For air cylinders, the problem of compressibility increases potential instability. In general, hybrid hydraulic systems are separated into parallel and series categories [9]. In a series circuit, the components are connected end to end in a single loop. valve When D. Exhaust flow from the cap end returns to the tank conventionally through the 3. 2 Valve control circuits 138 4. In a parallel circuit, the components are connected side by side, providing multiple paths for current to flow. In this example, the oil flow (eg 60 LECTURE 24 TO 26 - HYDRAULIC CIRCUIT DESIGN FREQUENTLY ASKED QUESTIONS 1. There is only one path for the current to flow.
