HYDRAULISKT ARBETANDE APPARAT AVSEDD ATT LOSSTAGBART HOPMONTERAS MED EN VRIDMOMENTVEXELANORDNING FOR EFFEKTOVERFORING MELLAN DESAMMA

摘要

Quick change hydraulic connection apparatus suitable for removably mounting a rotatable hydraulic unit into fluid sealed relation with a complementary rotatable torque exchange device and also mounting said unit into torque transmitting relation with said device; includes a fluid manifold defining a plurality of manifold passages for fluids and connectable by fastener means between the device and the unit; the unit defines a plurality of unit passages for fluids which are adapted for registry with the manifold passages upon axial connection of the unit with the manifold; each passage of the manifold passages and the unit passages has complementary valve means to selectively close each respective passage upon disconnection of the unit from said manifold and to permit fluid flow through each respective passage when said unit and said manifold are connected into operative condition.
