Abstract

Dans le bloc-cylindres coulissent les pistons qui délimitent les chambres de travail. Des chambres sont en communication avec l'ouverture d'admission 12 alors que les autres sont reliées au refoulement 13, sur la surface frontale 6a du plateau de distribution fixe 6. La surface 6a coopère avec celle du bloc-cylindres à ouverture de sortie 20 des chambres de travail. L'intervalle 23 des ouvertures d'admission et de refoulement comporte une ouverture auxiliaire 14. Chaque chambre de travail, dans la zone de l'intervalle 23, est reliée, par l'ouverture auxiliaire 14 en communication avec le réservoir 16 à travers l'étranglement 18, à l'ouverture de refoulement 13. La présente invention est particulièrement destinée aux circuits hydrauliques d'appareils volants ou submersibles.
