A hydraulic jack works by pumping fluid from a reservoir into a small cylinder, which then pressurizes a larger cylinder. A full stroke of the smaller piston creates a small stroke of the larger piston, creating a mechanical advantage. The mechanical advantage allows the jack user to lift an object (i.e. a car) much heavier than they would otherwise be able to lift by themselves, just by lifting it a tiny bit at a time. The fluid pumped into the larger cylinder is prevented from escaping by a valve, which can then be opened allowing the fluid to return to the reservoir when the user is ready to lower the object, or vehicle.
Logic valves serve as a multifunctional valve for controlling the direction, flow and pressure by controlling the pressure signals in a hydraulic system, at the same time providing protection to the hydraulic pump.
Purge slowly into a pail or bucket in the telemotor hydraulic system purging valve until such a time pure hydraulic oil are coming out from the purging valve.
No-one created circuit symbols; they evolved over time. And, in fact, different countries use different standards for their symbols so US standard symbols, for example, are different from European standards.
Hydraulic literally means 'moving fluid'. A volume of fluid that is displaced by another given volume, be it solid or fluid, has a flow of that volume of displacement measured in volume / time. For example: litres / minute. A hydraulic pump may provide a flow of 10 litres per minute. This flow may be turbulent or laminar. Do not confuse this with pressure.
