Beschreibung
Zusammenfassung:	The invention relates to a lubrication system (30) for a turboprop engine, including an oil supply device (33) for at least one enclosure (32) and equipment (31), the equipment (31) being linked to the supply device (33) via a displacement pump (35), characterized in that the lubrication system (30) includes a pressure limiting valve (36) installed downstream from said displacement pump (35) and parallel to the equipment (31), so that the oil circulates through the equipment (31) when the equipment is active, and through the valve (36) when the equipment (31) is inactive. L'invention concerne un système de lubrification (30) pour turbopropulseur, comportant un dispositif d'alimentation en huile (33) d'au moins une enceinte (32) et d'un équipement (31), l'équipement (31) étant lié au dispositif d'alimentation (33) via une pompe volumétrique (35), caractérisé en ce que le système de lubrification (30) comporte un clapet (36) limiteur de pression monté en aval de ladite pompe volumétrique (35) et en parallèle de l'équipement (31), de sorte que l'huile circule par l'équipement (31) lorsque celui-ci est actif, et par le clapet (36) lorsque l'équipement (31) est inactif.
