Rdil piston pumps Model R4 consist of housing (), cm shft () nd, or 0 piston elements () with suction plte (4), high pressure check () nd piston shoe (6). uction nd delivery process iston (6) nd ssembly () re rrnged rdilly to the cm shft (). Hollow piston (6) with suction plte (4) is guided by cylinder () nd held upon the cm shft () by spring (8). The rdius of the piston shoe corresponds to the cm shft rdius. The cylinder () sels ginst hemisphericl element (9). When piston (6) extends, volume (0) in cylinder () increses. The resulting negtive pressure permits the suction vlve plte (4.) to open. As piston (6) extends, fluid is drwn from the cse () nd enters piston ssembly () vi groove () on the cm shft. During piston trvel to the top of the cm lobe, groove () is unvilble nd volume (0) is compressed forcing fluid beyond high pressure check () nd ultimtely to the system. Ech piston ssembly cn provide flow in this mnner
