He mea hoʻoheheʻe wahie nona ka pā puka e kokoke ana i ka puka. Loaʻa i ka pā orifice nā ʻili papa mua a me ka lua i hoʻokaʻawale ʻia ma kahi mamao i koho mua ʻia mai kekahi i kekahi a me kahi puka, e hohola ana ka puka ma kahi axis longitudinal a loaʻa kahi ʻili mua a me ka ʻili lua e hoʻokaʻawale ʻia mai ka ʻili mua. Aia ka ʻili mua i kahi ʻāpana mua me kahi ʻano o ka ʻili mua e kuhikuhi ʻia ana ma kahi ʻaoʻao mua oblique i ke axis longitudinal. Aia ka ʻili lua i kahi ʻāpana ʻelua me ka ʻano ʻili lua e kuhikuhi ʻia ana ma kahi ʻaoʻao ʻelua oblique i ke axis longitudinal. ʻO ka mea hoʻoheheʻe wahie he hale e hohola ana i kahi axis longitudinal. Aia i loko o ka hale kahi puka komo, puka a me kahi alahele i waiho ʻia ma waena o ka inlet a me ka puka. Hoʻokomo pū ka mea hoʻoheheʻe wahie i kahi mea hana electromagnetic e pili ana i ka inlet, ka mea hana electromagnetic me kahi armature a me kahi coil electromagnetic kahi hui valve, ka hui valve me kahi lālā pani a me kahi noho valve, hiki i ka lālā pani ke hoʻopaʻa i ke kahe wahie i ka puka. kahi kūlana mua a hiki ke hoʻokahe i ka wahie i ka pā puka ma kahi kūlana ʻelua. Ua wehewehe ʻia kekahi mau ʻano o ka hana ʻana i nā puka kihi i loko o kahi ʻāpana metala kahi e hiki ai ke hana ʻia kahi puka kihi mai kahi puka kihi ʻākau i hana mua ʻia. He axis oblique ko kēlā me kēia puka kihi e pili ana i hoʻokahi o ka ʻili mua a me ka ʻili lua o ka ʻili metala.
