Abstract
A hydraulic motor ( ), has an output shaft ( ), a block cylinder ( ), and high-pressure pistons ( ) guided therein, and a block cylinder spring ( ) and a valve plate ( ). The block cylinder ( ) exerts a contact-pressure force on the valve plate ( ) by way of the charging pressure of the hydraulic oil in the block cylinder ( ) and of the spring force of the block-cylinder spring ( ). The contact-pressure force is counter-acted, when the hydraulic motor ( ) is at a standstill, by a hydraulic pressure field which is built up on a surface ( ) between the block cylinder ( ) and the valve plate ( ) via a valve device ( ).
