Abstract
A hydraulic machine is described having a first part () and a second part () moveable relative to said first part (), one of said first part () and said second part () having a first land () resting against the other one of said second part () and said first part (), having a predetermined first height (H), and being arranged between a high pressure area () and a low pressure area (). Such a machine should have a long working life. To this end a second land () having a predetermined second height (H) smaller than said first height (H) is located adjacent to said first land ().
