Abstract (en)

[origin: EP0690248A1] The transmission has a hydraulic circuit (1) that is divided into first and second circuits (I). The first is a discontinuous scavenging circuit, connected to an external pressure medium source (11). The second separate circuit is a continuous scavenging and feed circuit (II), which is dependant upon the leakage flow from the hydraulic pump (7). The second circuit is connected to a distribution pipe (17), via a feed pipe (12), which is connected to the source. The distribution pipe has branches (13,14), each with a valve (15,16), leading to the two working pipes (3,4). The pump is a variable axial piston pump. <IMAGE>
