摘要： An axial piston micropump (100) is disclosed, having a cylinder drum (2), in which several cylinders (41, 42) are provided, and a swash plate (1), with respect to which the cylinder drum (2) is rotatable. It is desirable for such a micropump to have a small displacement combined with a long service life and in which the displacement or delivery volume can be achieved with great accuracy. For that purpose, at least two cylinders (41, 42) are provided, of which at least one is in the form of a working cylinder (41) which has an associated working piston (3), whilst at least one other cylinder is in the form of a balance cylinder (42) and has an associated balance piston (4).

摘要： Two synchronous hydraulic polyphase motor-generators with axial cylinders are connected by rigid or flexible pipes. One functions as a generator, the other as a motor to transmit torque and power. Sinusoidal piston motion is developed without the use of cams. The pistons cause columns of fluid to alternate between motor and generator, producing synchronous rotation. Apparatus for synchronizing, coupling and decoupling the motive force are disclosed.
