CYLINDER BLOCK COMPRISING PISTON-HOLDING MEANS

The invention relates to an assembly comprising: a cylinder block (10), a plurality of pistons (20), and a holding element (30) extending over all or part of the outer periphery of the cylinder block(10); the holding element (30) comprising a plurality of guide portions (36) each partially blocking a recess (12) of the cylinder block (10), so as to engage with a planar end (26) of the crown (24)of a piston (20) so as to guide the translation of each of the pistons (20) in its respective recess (12). The holding element (30) comprises two indexing means (36) engaging with two indexing means (16) of the cylinder block (10) so as to hold the holding element (30) under a traction force when positioned around the cylinder block (10). 本发明涉及一种组件，其包括：缸体(10)、多个活塞(20)以及保持元件(30)，保持元件(30)在缸体(10)的整个外周或部分外周上延伸；保持元件(30)包括多个引导部(36)，每个引导部部分地阻挡缸体(10)的凹部(12)，以便与活塞(20)的冠部(24)的平面端(26)接合，从而引导每个活塞(20)在其各自的凹部(12)中的平移。保持元件(30)包括两个分度装置(36)，该两个分度装置(36)与缸体(10)的两个分度装置(16)接合，以便使保持元件(30)在围绕缸体(10)定位时在牵引力的作用下被保持。
