Splet01. jan. 2004 · In order to investigate the leaking characteristics of the port plate pair in primary three-row axial piston pump/motor, the present paper deducts two equations about the leakage of oil film ... Splet01. jan. 2024 · Compared with other types of axial piston pumps, swash-plate type piston pumps are more popular because of their simple structure and convenient flow regulation. 1 Therefore, this review is focused on the swash-plate type piston pump. As shown in Fig. 1 (b), a swash-plate axial pump consists of several pistons nested in the cylinder block at ...
The swashplate engine uses a swashplate in place of a crankshaft to translate the motion of a piston into rotary motion. Internal combustion engines and Stirling engines have been built using this mechanism. Duke Engines has been working on such a platform since 1993. The axial piston pump drives a series of pistons aligned parallel with a shaft through a swashplate to pump a fluid. A common example of a swashplate application in a fluid pump is the compressor of … SpletSwash plate actuator arm The distance between the actuator line of action and the center of the rotor rotation. The parameter must be greater than zero. The default value is 0.065 m. Piston pitch radius The radius of the pitch circle where the pistons are located, that is, the cylinder block pitch radius. The parameter must be greater than zero.
SpletSwash plate pumps have a rotating cylinder containing pistons. A spring pushes the pistons against a stationary swash plate, which sits at an angle to the cylinder. The pistons suck …
