Title: Improvements in power transmission systems embodying hydraulic couplings
IPC: F16D33/16
Filed: 1938-02-24
Abstract: 511,858. Hydraulic power transmitters. DAIMLER-BENZ AKT.-GES. Feb. 24, 1938, No. 5898. Convention date, March 11, 1937. [Classes 69 (ii) and 135] A control arrangement for hydraulic couplings of the Fottinger type and of the kind in which a continuous circulation of liquid through the working chamber(s) of the coupling is maintained, the outlet therefrom being permanently open while the inlet or supply thereto can be controlled so as to vary the degree of filling-or liquid content-and therefore the slip during running, comprises two or more supply devices for the coupling one or some of which can be turned off or controlled so as to reduce the degree of filling whilst the remainder continues to charge the coupling with the reduced quantity of liquid. A blower a for an aircraft engine is driven by the engine through step-up gearing and a double-circuit coupling c, the blower delivering to the engine through a duct e, the pressure beyond a throttle f being controlled by adjusting the throttle by hand or other means. The coupling is supplied with working liquid by two pumps h, i mounted on a common shaft driven by the engine; the delivery of the pump i can be short-circuited to the reservoir g by means of a cock n, whereby the coupling is supplied only by the pump h and its filling is reduced. Alternatively the cock n may divert the delivery of pump i to a passage p terminating in jets directed towards the exterior of the coupling for cooling the couplng, as described in Specification 511,859. The cock n may be moved by hand or automatically, as e.g., by connection with a barometric capsule q in a housing connected by a duct r with the atmosphere or with the blower delivery passage in front of or beyond the flap f. The barometric capsule may be substituted by a simple diaphragm, a spring-loaded piston or any other pressure sensitive device. Two flaps may be used in the blower duct, one of these being adjusted by hand and the other in dependence on the external or charging pressure. The cock may be actuated by a fluid-pressure servomotor; an over-riding manual control may be provided. Instead of a simple change-over cock, a gradually or progressively controllable throttle valve or the like may be employed. Three pumps may be employed, minimum filling being obtained with one in use, normal fillng with two and maximum filling with three. The liquid for the coupling may be obtained from any suitable source, e.g., the lubricating oil container of the internal combustion engine. Specification 378,754 also is referred to.
