Subject: pull a vacuum against a portion of a seed disc agric. The seed side housing and vacuum side housing are preferably releasably mounted to the frame, e.g., by engaging an arm of the seed side housing to a deflectable mounting tab fixed to the frame. The vacuum side housing preferably includes a vacuum inlet placing the interior of the vacuum side housing in fluid communication with a vacuum source (e.g., an impeller) which pulls a vacuum against a portion of a seed disc.Как тут перевести which pulls a vacuum against a portion of a seed disc? Застопорило на pull against. |

как и написано - создает вакуум/пониженное давление на участке диска (сеящего или какого там у вас). крылчатка вертится, тянет из камеры (корпуса), чем создает пониженное давление в этой зоне, откуда тянет. |
