Ma valve a pulse amagawidwa kukhala ma valve a kumanja ndi ma valve omwe ali pansi pamadzi.
Mfundo ya ngodya yakumanja:
1. Pamene valavu ya pulse ilibe mphamvu, mpweya umalowa m'chipinda cha decompression kupyolera mu mipope yosalekeza ya zipolopolo zam'mwamba ndi zam'munsi ndi mabowo otsekemera.Chifukwa chapakati cha valve chimatchinga mabowo opumira pansi pa kasupe, mpweya sudzatulutsidwa.Pangani kupanikizika kwa chipinda cha decompression ndi chipinda chapansi cha mpweya mofanana, ndipo pansi pa kasupe, diaphragm idzatsekereza doko lowombera, ndipo mpweya sudzathamanga.
2. Vavu ikapatsidwa mphamvu, valavu imakwezedwa pansi pa mphamvu ya electromagnetic, bowo lothandizira limatsegulidwa, ndipo mpweya umatulutsidwa.Chifukwa cha zotsatira za nthawi zonse kuthamanga chitoliro orifice, outflow liwiro dzenje mpumulo ndi chachikulu kuposa cha kupanikizika kwa chipinda.Kuthamanga kwa mpweya wa chitoliro cha chitoliro kumapangitsa kuti kupanikizika kwa chipinda cha decompression kutsika kusiyana ndi kupanikizika kwa chipinda chapansi cha mpweya, ndipo mpweya womwe uli m'chipinda chotsika cha gasi umakankhira mmwamba pa diaphragm, umatsegula doko lowombera, ndikuwombera mpweya.
