A fluid working machine, operable to carry out a motoring cycle under at least some circumstances, comprises a controller (12) and a working chamber (2) of cyclically varying volume. The working chamber has a high pressure valve (18) as-sociated therewith to control the connection of the working chamber to a high pressure manifold (20), and an electronically con-trollable primary low pressure valve (14) to control the connection of the working chamber to a low pressure manifold. The con-troller is operable to actively control at least the primary low pressure valve, in phased relationship to cycles of working chamber volume, to determine the net displacement of fluid by the working chamber on a cycle by cycle basis. The fluid working machine is adapted to release pressurised fluid from the working chamber prior to the opening of the primary low-pressure valve, during a motoring cycle. This facilitates the opening of the primary low pressure valve.

L'invention concerne une machine de travail à fluide conçue pour effectuer un cycle motorisé dans au moins un certain nombre de circonstances, qui comprend une unité de commande (12) et une chambre de travail (2) dont le volume varie de manière cyclique. La chambre de travail possède une soupape haute pression (18) qui lui est associée pour commander la connexion de la chambre de travail à un collecteur haute pression (20), et une soupape basse pression primaire régulable électroniquement (14) pour commander la connexion de la chambre de travail à un collecteur basse pression. L'unité de commande peut commander activement au moins la soupape basse pression primaire, en phase avec les cycles du volume de la chambre de travail, pour déterminer le déplacement net du fluide par la chambre de travail sur une base de cycle par cycle. La machine de travail à fluide est conçu pour libérer le fluide sous pression de la chambre de travail avant l'ouverture de la soupape basse pression primaire, pendant un cycle motorisé, ce qui facilite l'ouverture de la soupape basse pression primaire.
