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 ...
The swash plate angle will remain at the maximum allowed, and the pistons will operate at full stroke. This continues until system flow-demand eases and the pump's capacity is greater than demand. As the pressure rises the swash-plate angle modulates to try to not exceed the maximum pressure while meeting the flow demand. [2]
A swash plate drive employs an axial piston pump or motor in which the swash plate angle can be changed to adjust the displacement and thus adjust the speed. Hydrodynamic drives or fluid couplings use oil to transmit torque between an impeller on the constant-speed input shaft and a rotor on the adjustable-speed output shaft.
A common type of variable-displacement pump used in vehicle technology is the axial piston pump. This pump has several pistons in cylinders arranged parallel to each other and rotating around a central shaft. A swashplate at one end is connected to the pistons. As the pistons rotate, the angle of the plate causes them to move in and out of ...
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 ...
That implies the following main applications for a radial piston pump: machine tools (e.g., displace of cutting emulsion, supply for hydraulic equipment like cylinders) high pressure units (HPU) (e.g., for overload protection of presses) test rigs; automotive sector (e.g., automatic transmission, hydraulic suspension control in upper-class cars)
When you think of a vending machine, things like snacks, sodas, or even pharmaceutical supplies may come to mind. But you might be surprised to know that the first ever vending machine actually ...
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]
