초록 ▼

A pump for use with a container of liquid material for dispensing and or atomizing the liquid material in an accurate dose. The apparatus has a movable valve member which is normally biased in a closed position. Upon actuation of the pump, a fluid pressure is caused to act upon the valve member. The ratio of the area of the valve member against which the pressure acts before and after opening of the valve member is selected to be at least 1:1.5, to cause a corresponding reduction of the force necessary to open the valve and dispense the fluid upon actuation, resulting in a full stroke and single puff each time.

A pump for use with a container of liquid material for dispensing and atomizing the liquid material in an accurate dose per operation comprising: (a) means defining a pump chamber of substantially fixed volume, with a closed radial sidewall and an inner end, said pump chamber having an opening at its inner end; (b) means for filling said pump chamber; (c) a pump stem having a piston on one end thereof disposed for reciprocal motion in said pump chamber; (d) said pump stem having a passageway therethrough with a dispensing outlet at the outer end of said passageway and an axial inlet port located inwardly thereof; (e) a rigid valve member having a first end portion cooperating with said axial inlet port to close off said axial inlet port and a second end portion of a predetermined cross-sectional sealing area, the axial length of said second end portion of predetermined cross-sectional area being at least equal to the range of movement of said pump stem over which dispensing occurs; (f) means forming a seal at said opening at the inner end of said pump chamber, said second end portion of said valve member passing through said seal where said second end portion is sealingly guided; (g) means for supplying liquid in a container to said means for filling; (h) means biasing said valve member outwardly so that the first end portion thereof closes off a cross-sectional area of said axial inlet port; (i) the cross-sectional area closed off at said axial inlet port being smaller than the cross-sectional area of said second end portion of said valve member where it is sealingly guided, whereby, as said pump is operated by said pump stem, the pressure in the pump chamber is increased until, at a predetermined pressure, said means biasing said valve member is overcome and said valve member is moved away from said pump stem to open said axial inlet port and permit pressurized material to be discharged through said passageway and dispensing outlet; and (j) means for causing the force necessary to move said stem inwardly before said port is opened to be at least 1.5 times the force needed to move said stem when said inlet port is opened.
