Ioniq Concept Cabin

A Hyundai's project Ioniq has unveiled the IONIQ Concept Cabin, its latest vision of the future.

Engineers have announced that the car is equipped with the ceiling-mounted screen, which is large enough for two people to enjoy different content simultaneously. The sound is pumped through the speakers, which provide personal sound zone.

In addition, a floor cleaning robot ensures the cabin is kept clean and disinfected.

The piston pump

When the piston moves upward, the liquid under atmospheric pressure enters the tube, lifts the bottom valve and moves behind the piston.

When the piston moves downward, the liquid under the piston presses on the bottom valve and it closes.
At the same time, the pressure of the fluid opens the valve inside the piston, and this fluid moves into the space above the piston.
