Hydraulic gear machine e.g. external gear pump, for e.g. generating hydraulic energy, has actuator device to adjust axis position during machine operation and working against shaft deflection forces, where shafts center distance is changed

Gear machine, particularly external gear pump or external gear motor, has housing provided on outer surface with trough-like depression, and a low pressure connection is arranged at deepest point of trough-like depression

Hydraulic Toothed Wheel Machine

Hydraulic gear wheel machine i.e. external gear wheel machine such as external gear wheel motor, for generating and converting of hydraulic energy, has actuators adjusting opening independent of operating pressure during machine operation

Gear machine e.g. pump is formed with recess with two portions extended in different directions, such that pressurized fluid pass into recess in direct contact with bearing sleeve and tooth space of associated gearwheel

Geared machine with hydrodynamic and hydrostatic bearing pins

Gear wheel machine e.g. pump, has housing comprising resilient wall section arranged in region of tip cylinder diameter of assigned gear wheel and made of elastomer material, and gear wheels that are combined with one another

Hydraulic gear wheel machine e.g. external gear pump, for producing or transforming hydraulic energy in mobile hydraulics, has changing device with actuator for changing chamber volume or for increasing connection to pressure relief line

Gear wheel machine e.g. pump or motor, has two gear wheels combining with one another, and contact element comprising piston that is accommodated in pressure-tight manner and linear movable with respect to bore of housing

Gear machines with improved kinematics
