Figure 1A is a longitudinal sectional view, Figures 2A and B are examples of valves with the same function but different shapes of main parts, Figure 3 is a sectional view of a known example, and Figure 4 is a conventional valve. FIG. 1 is valve housing, 2 is solenoid, 4 is rod, 1T
, 1P is a passage, 11 is a valve seat, 6 is a plug, 61 is a projection, 7 is a valve, 8 and 10 are springs, 12 is a sub-valve, and a and b are air passages.
Claims (1)
電磁弁において、バルブ内にばね圧下にてサブバ
ルブを摺動可能に嵌挿し、このバルブを嵌挿支持
したプラグ内にサブバルブ背面と対向し大気と通
ずる通路を形成した突起を設けると共に、閉弁時
真空ポンプ側通路の真空を破壊する通路をバルブ
７に形成した真空用電磁弁。 In a solenoid valve that opens and closes the valve by the action of a solenoid, a sub-valve is slidably inserted into the valve under spring pressure, and a passageway facing the back of the sub-valve and communicating with the atmosphere is provided inside the plug that supports this valve. A vacuum solenoid valve is provided with a protrusion having a shape formed therein, and a passage is formed in the valve 7 to destroy the vacuum in the vacuum pump side passage when the valve is closed.
