摘要:
A hydrodynamic machine contains a bladed primary wheel driven by a rotary shaft and a bladed secondary wheel, which together form a work chamber filled with a working medium. The machine has a pressure pump for delivering a working medium from the work chamber. The pressure pump has a first inlet, which projects into the work chamber, and has a first inlet opening which is aligned with the rotary shaft in the circumferential direction. The pressure pump has a second inlet which projects into the work chamber and has a second inlet opening which is aligned to the rotary shaft in the circumferential direction opposite to the first inlet opening. The first and second inlets are joined to a common working medium channel behind the two inlet openings. The first and second inlets extend adjacent to each other in the same flow direction separated by a separation wall.

A hydrodynamic coupling having a constant quantity of working fluid, the coupling comprising, a pump wheel and a turbine wheel which together form a working space for a working fluid, a first storage chamber in fluid communication with the working space; and a valve for displacing working fluid between the working space and the storage chamber in response to an external control during operation of the coupling; and further comprising a housing which is connected, fixed for rotation, with the pump wheel, the housing including the first storage chamber, the first storage chamber being rotatable with the housing.

A scoop controlled fluid coupling has a toroidal working circuit W defined by vaned impeller and runner elements 11,12. Working liquid is supplied to the working circuit W from a rotating reservoir 9 by an adjustable scoop tube 15 having a scooping orifice 16, the radial position of which is to determine the degree of filling of the circuit W. To counteract unintentional changes in the filling due to thermal expansion of the liquid, the runner diameter is about 10% smaller than that of the impeller, and the runner has two sets of holes 54,55 which permit liquid to escape from the circuit.

The trimming scoop of a scoop-trimmed fluid coupling is interconnected with a movable weir tube in an overhead reservoir to effect complementary changes in the volumes of liquid in the reservoir and the working circuit or circuits of the coupling on movement of the weir tube and scoop tube in either direction. A cooling flow path may extend from the reservoir to the working circuit or circuits.
摘要:
A fluid coupling equipped with means for admitting liquid to the work chamber at a variable rate for effecting quick output speed changes. The admitting means includes a rotating reservoir containing a reserve ring of liquid, and a scoop tube movable into the reservoir to extract liquid from the ring at a variable rate in accordance with the scoop tube position, and the replenishment rate for the reservoir.
