Abstract (en)

[origin: WO2017027424A1] A method of dispensing a continuous fluid flow is described, the method includes: (i) filling a first cylinder chamber, having a first predefined volume, with fluid received through a first manifold from a first fluid inlet; (ii) dispensing the first predefined amount of the fluid present inside the first cylinder chamber through the first manifold to a fluid outlet; (iii) filling a second cylinder chamber, having a second predefined volume, with fluid received through a second manifold from a second fluid inlet, and wherein filling is carried out contemporaneously with dispensing; (iv) exerting, during dispensing, a deflection-causing force on a first housing that is disposed adjacent to the first cylinder chamber; and (v) preventing, using the deflection-prevention feature, transfer of the deflection-causing force from the first housing to a second housing, which is disposed adjacent to the second cylinder chamber and is disposed adjacent to the first housing.
