Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...

There are two specialized types of hydraulic intensifier used for water jet cutting. The first and most common is the inline hydraulic intensifier. Oscillating hydraulic pistons are used to compress water to the required pressure levels. The water jet system's cutting head restricts the water flow to generate pressure and direct it onto the ...
However, many hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for working pressure at both sides of the motor, whereas most hydraulic pumps rely on low pressure provided from the reservoir at the input side and would leak fluid when abused as a motor.

The Invisible Thread is an autobiography written by Yoshiko Uchida and published in 1991. The book is a memoir of her childhood during World War II. [1]It describes her childhood in Berkeley as a second-generation Japanese American [2] and her life after she and her family were sent to a Japanese internment camp after the attack on Pearl Harbor.
