Abstract

An electromagnetic valve includes a solenoid; a sealing portion provided on a movable element; an urging member; a first pipe including a first outlet side end portion; and a second pipe including an inlet side end portion and a second outlet side end portion. The first pipe includes a receiving seat being in close contact with the sealing portion. In a first state where the sealing portion is separated from the receiving seat, a liquid flows to the first outlet side end portion. In a second state where the sealing portion is in close contact with the receiving seat, the liquid flows to the second outlet side end portion and does not flow to the first outlet side end portion, and a pressing force by the urging member and a hydrostatic pressure of the liquid in the merging portion act to press the sealing portion against the receiving seat.

Claims (21)

1. An electromagnetic valve, comprising:

a solenoid including a movable element configured to move relative to a stator;

a sealing portion provided on the movable element;

a spring;

a first pipe including a first outlet side end portion on a downstream thereof; and

a second pipe including an inlet side end portion on an upstream thereof and a second outlet side end portion on a downstream thereof, wherein

the first pipe includes a receiving seat configured to be in close contact with the sealing portion,

a merging portion where the first pipe and the second pipe merge is provided upstream of the receiving seat of the first pipe,

the sealing portion is configured to move to a position that is in close contact with the receiving seat and a position that is separated from the receiving seat,

the sealing portion is pressed against the receiving seat by the spring,

in a first state where the sealing portion is separated from the receiving seat, a liquid flowing in from the inlet side end portion is allowed to flow to the first outlet side end portion through the merging portion,

in a second state where the sealing portion is in close contact with the receiving seat, the liquid flowing in from the inlet side end portion is allowed to flow to the second outlet side end portion through the merging portion, and does not flow to the first outlet side end portion, and

in the second state, a pressing force by the spring and a hydrostatic pressure of the liquid in the merging portion act to press the sealing portion against the receiving seat.

2. A vehicle cleaner system, comprising:

an upstream branch portion including the electromagnetic valve according to claim 1 ;

a tank connected to the inlet side end portion of the electromagnetic valve of the upstream branch portion and configured to store a cleaning medium;

an upstream cleaner unit connected to the first outlet side end portion of the electromagnetic valve of the upstream branch portion;

a downstream branch portion including the electromagnetic valve according to claim 1 ;

a connecting portion connecting the second outlet side end portion of the electromagnetic valve of the upstream branch portion and the inlet side end portion of the electromagnetic valve of the downstream branch portion;

a downstream cleaner unit connected to the first outlet side end portion of the electromagnetic valve of the downstream branch portion; and

a blocking portion provided at the second outlet side end portion of the electromagnetic valve of the downstream branch portion and preventing the cleaning medium from the second outlet side end portion of the electromagnetic valve of the downstream branch portion from being discharged to an outside.
