Hydraulic ram
- Momentum of water
- whose flow, cyclically closed,
- rams water past a check valve
- up a hill,
- and regulates itself
- as the waste valve
- is first closed by the flow
- and then opened as it falls.
Water hammer
- Pulsation engine
- Self-acting ram pump
- Water hammer
- Water ram
- Hydrolic ram
- Hydram
- operates
- with only water flow—
- look Ma, no hands.
Hydraulic thump
- Water rushes
- down the pipe and THUMP
- past the check valve and up toward the attic of the house.
- Before electricity
- came to the farm and THUMP
- water users had to make clever use of gravity.

Joseph-Michel Montgolfier and his brother Jacques-Étienne owned a paper mill in Voiron and developed the first manned untethered flight of a hot-air balloon. The balloon was made of paper. Joseph-Michel invented the first self-acting water ram to raise water at their paper mill. Early water rams cycled every minute or so, producing a loud thump with each cycle.
