PROBLEM TO BE SOLVED: To provide a pulsator for milking, which has a small power consumption, is driven by a battery, is light, easily used and has high durability.SOLUTION: The electronic pulsator alternately connects a pulsation vacuum tube to a vacuum source and an atmospheric pressure, provides a pulsation pressure, includes a first air chamber A furnished with a vacuum pressure supply port 13c communicating with the vacuum source and an atmospheric air inlet 13f, a second air chamber B communicating with the first air chamber A by an air communication hole 13d and a third air chamber C communicating with the pulsation vacuum tube, in a housing 1. The first air chamber A has a rotary slider 4 that is fixed on the rotating shaft of a latching rotary solenoid 3 and selectively communicates the air communication hole 13d to the vacuum pressure supply port 13c and the atmospheric air inlet 13f based on the rotational position and a valve body 6a connected to a diaphragm 5 having the second air chamber B as a pressure change part that selectively communicates the third air chamber C to the vacuum source and the atmospheric air.COPYRIGHT: (C)2010,JPO&INPIT【課題】消費電力が小さくバッテリー駆動でき、かつ軽量で使いやすく耐久性の高い搾乳用パルセータを提供する。【解決手段】拍動真空チューブを真空源と大気圧とに交互に接続して拍動圧を与える電子式パルセータであって、ハウジング1内に、真空源に連通する真空圧供給口13cと大気導入孔13fとを備えた第一の空気室Aと、空気連絡孔13dにより第一の空気室Aに連通された第二の空気室Bと、拍動真空チューブに連通する第三の空気室Cとを備え、前記第一の空気室Aにはラッチング式ロータリーソレノイド3の回転軸に固定されて回転位置により前記空気連絡孔13dを真空圧供給口13cと大気導入孔13fとに選択的に連通させる回転式スライダ4が設けられ、前記第二の空気室Bを変圧部とするダイヤフラム5に連結した弁体6aが前記第三の空気室Cを真空源と大気に選択的に連通させる電子式パルセータ。【選択図】図1
