Abstract (en)
[origin: EP0445529A1] The hydraulic device has a gear pump (10), the delivery flow of which can be controlled with the aid of a sealing plate (31) which can be placed against the side faces of the gear. This is effected with the aid of a control pressure produced by a pressure balance (24) which is subjected, on the one hand, to the delivery pressure of the pump and, on the other hand, for example, to the load pressure at loads. An internal bypass which depends on the distance between the sealing plate and the side faces of the gear and effects control of the delivery rate is created. <IMAGE>
