<p>1. A single or multicylinder radial pump including a body (1) in which is rotatably mounted a shaft (2) having at least one excentric or a control cam (3), at least one piston (13) mounted for sliding with respect to the body (1) and subjected to the action of resilient means (14) tending to apply it against the excentric and a discharge device including a valve seat (18), a valve (21) urged towards its seat by resilient means (26), a valve cage (24) and an output connection plug (30), characterized in that the piston (13) is mounted for sliding in a bore (12) formed directly in the pump body (1) and in that this bore (12) is extended by a second bore (16) of larger diameter in which the discharge device is disposed, this latter being held in position against the resilient means (14) of the piston by the connection plug (30) which is sealingly fixed in this second bore (16).</p> |
