Abstract
A hydraulic apparatus including a machine shaft having a proximal end and a distal end, adapted to drive a cylinder block. A clutch having a clutch shaft having a proximal end and a distal end, and a plurality of friction discs linked to the distal end of the clutch shaft and a plurality of friction discs linked to the proximal end of the machine shaft for selectively engaging the clutch shaft with the machine shaft. The friction discs are disposed radially around the machine shaft. The distal end of the clutch shaft is bell-shaped so as to surround the proximal end of the machine shaft. The bell shape defines an inner space where the proximal end of the machine shaft and the friction discs linked to the clutch shaft are located.
