A traditional hydraulic ram has only two moving parts, a spring or weight loaded "waste" valve sometimes known as the "clack" valve and a "delivery" check valve, making it cheap to build, easy to maintain, and very reliable. Priestly's Hydraulic Ram, described in detail in the 1947 Encyclopedia Britannica, has no moving parts. [9]

The steering rack is almost conventional. As with a normal power-assisted steering setup, there is a rack-and-pinion, and a stepped hydraulic ram with a dividing plate (the piston) in the middle. On one side of the plate, the piston area is half the area of the other, giving twice the area for the fluid to work on.
A spreader is a hydraulic tool that is designed with two arms that come together in a narrow tip, and that uses hydraulic pressure to separate or spread the arms. The tip of the tool can be inserted into a narrow gap between two vehicle panels (such as between two doors, or between a door and a fender), then operated to create or widen an opening.
Punch presses are large machines with either a 'C' type frame, or a 'portal' (bridge) type frame. The C type has the hydraulic ram at the top foremost part, whereas the portal frame is much akin to a complete circle with the ram being centered within the frame to stop frame deflection or distortion.
You recycle your plastic iced tea bottles. Of course you carry a reusable bottle for water. You compost the scraps from your locally sourced, organically grown vegetables.
Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria. [ 1 ] Heron studied the pressure of air and steam, described the first steam engine , and built toys that would spurt water, one of them known as Heron's fountain.
