Transfer of energy between the fluid and the machine by means of a variable volume, generated by a displacement device.
You'll find further information on this topic at the right.
Piston compressors deliver compressible media such as gas or air. Piston compressors are positive displacement machines. The piston (displacement element) forms a space with variable volume together with cylinder and cylinder cover.
In positive displacement pumps the energy is transferred to the fluid hydrostatically. In the hydrostatic transfer of energy a displacement body reduces a working chamber filled with fluid and pumps the fluid into the pipe.
Engineering animations such as cutaway models are ideally suited to representing processes and functions. GUNT uses up-to-date original parts for its cutaway models. Movement and switching functions are maintained.
