CAM OPERATED PURGING PUMP

摘要

A pump (100) comprises a housing (101) with at least one inlet valve (102) and one outlet valve (103). A membrane (104) which is positioned within the housing (101) and forms a pumping chamber for receiving fluid from inlet valve (102) and pumping fluid out from outlet valve (103). A follower (105) is attached to the membrane (104) on opposite side of the inlet valve (102) and outlet valve (103) and adapted to reciprocate inside housing (101). A rotating member (106) is attached to a cam shaft (107) which is arranged for the rotation inside the follower (105) and the rotating member (106) should be in constant contact with the follower (105) so that the follower (105) reciprocates with the help of rotating member (106) and an element (108) to aid reciprocation of the follower (105) and located in between the follower (105) and housing (101).
