2. Swashplate - Wikipedia

   en.wikipedia.org/wiki/Swashplate

   The axial piston pump drives a series of pistons aligned parallel with a shaft through a swashplate to pump a fluid. [4] A common example of a swashplate application in a fluid pump is the compressor of a present-day automobile air conditioning system. By varying the angle of the swashplate, the pistons' stroke (and, therefore, the compressor's ...

3. Variable displacement pump - Wikipedia

   en.wikipedia.org/wiki/Variable_displacement_pump

   If the swashplate is perpendicular to the axis of rotation, no fluid will flow. If it is at a sharp angle, a large volume of fluid will be pumped. Some pumps allow the swashplate to be moved in both directions from the zero position, pumping fluid in either direction without reversing the rotation of the pump.

   Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.

5. Hydraulic machinery - Wikipedia

   The most common is the swashplate pump. A variable-angle swashplate causes the pistons to reciprocate a greater or lesser distance per rotation, allowing output flow rate and pressure to be varied (greater displacement angle causes higher flow rate, lower pressure, and vice versa). Radial piston pump: normally used for very high pressure at ...

6. Axial engine - Wikipedia

   en.wikipedia.org/wiki/Axial_engine

   The Cylindrical Energy Module (CEM) is a sine-wave swashplate engine that can also be used as a standalone pump, powered by an external source. The rotating swashplate rotor assembly is moved back and forth with the help of piston drive pins, which follow a stationary sinusoidal cam track that encircles the rotor assembly. [citation needed]

7. Thermodynamic pump testing - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_pump_testing

   The thermodynamic method is used for performance testing of pumps, flow meter calibration, system curve tests, and other applications. It is capable of achieving results with uncertainties of less than 1% in pump efficiency and less than 1.5% in flow [ 3 ] while being able to test piping configurations where other conventional pump testing ...
