Japanese Patent JPH0461202
Kind Code:
B2
Abstract:
The present invention relates to a flow divider for carrying out a load-independent division of a stream of hydraulic fluid, comprising a basic body including an internal bore, a central main connection and two outer consumer connections leading to said internal bore, and further comprising two approximately coaxial control pistons which are displaceably guided in said internal bore and which are each provided with a flow orifice and with at least one radial control opening, said control pistons being adapted to be moved towards each other and away from each other to a limited extent via a coupling device connecting said pistons. In the case of known flow dividers the coupling device consists of interengaging hooks which are rigidly formed on the control pistons, said hooks producing, however, eccentric forces for the control pistons in said internal bore, and said forces impair the control characteristics and the operating behaviour of the flow divider. The task is the provision of a flow divider in the case of which the control pistons can be displaced without any clamping forces being produced. In accordance with the invention, this task is solved by the feature that the support areas between the coupling device and the control pistons have a structural design similar to that of a ball and socket joint.
