ABSTRACT:
A variable flow valve includes a housing, a valve element, an urging member, a first valve, a second valve, and a guide flow passage. The housing has an inlet opening, and an outlet opening. The first valve and second valve are formed between the valve element and the housing. The valve element has a separator wall. The separator wall separates the inlet opening and the outlet opening, and makes the second valve together with the housing. The guide flow passage is disposed on an inlet-opening side of the separator wall, and connects the inlet opening with the outlet opening when the separator wall moves to open the communication between the inlet opening and the outlet opening. The variable flow valve can make fluids flow without generating any turbulent flow, and can cope with the increment/decrement of required breather-gas flow volume more accurately.
