Bellows pump for delivery of liquids |
摘要 |
The invention relates to a liquid delivery pump (1) connected to the neck of a container comprising: a cylindrical hollow body (2) defining a suction and compression chamber (5) communicating with outside through a liquid distribution channel (7); a manually actuated piston (8) slidingly coupled to said hollow body (2); elastic means (12) cooperating with a push button (83) connected to said piston; first valve means (13) adapted to connect said suction chamber (5) with a liquid suction tube (6); second valve means (14) adapted to connect said suction and compression chamber (5) with said distribution channel (7) during the delivery phase. Said distribution channel (7) has a first stationary part (71) made in the plug (23) and a second swinging part (30) consisting of a tube (13) having at the end facing the first stationary part (71) a substantially spherical body (32) whose outer surface closes the first stationary part when said second part is substantially perpendicular to the first part.
