Embodiment Construction

[0035] Referring to the drawings, non-pressurized mechanically actuated dispensing systems according to various embodiments of the present invention generally include a dispensing mechanism having a dispensing head 1 comprising a body or housing 2, an actuating mechanism 3 and a connection to The pump 4 on the inlet 5, which communicates with the interior of the liquid reservoir 6 containing a container 7 of fluid 8 to be dispensed. In certain embodiments, the dispensing head may also include an energy storage mechanism 9 and a loading mechanism 10 for actuating the energy storage mechanism 9 .

[0036]Apart from the differences described herein, the pump 4 may advantageously have a similar construction and pumping action as the pump described in WO2007 / 074363, which is hereby incorporated by reference. The pump 4 includes a stator 12 and a rotor 13 rotatably mounted in said stator. The stator 12 comprises a housing 14 delimiting chambers 15, 16, hereinafter referred to as ro...

Abstract

A manually actuated dispensing system for dispensing fluid (8) contained in a non-pressurized container (7). The dispensing system comprises a dispensing head (1) with a housing (2), a nozzle through which the fluid to be dispensed exits, a pump (4) mounted in the housing and a pump actuation mechanism (3), the pump comprising A rotor (13) capable of rotating and axially moving relative to the stator (12). The pump rotor comprises first and second axial extensions (17,18) of different diameters mounted in respective chambers (15,16) of the stator, mounted in the stator housing and sealingly surrounding the first and First and second seals (19,20) of a second axial rotor extension comprising liquid supply passages (22,24) which in combination with seal rings operate as valves, said The valve is able to open and close the communication between the pump inlet connected to the interior of the container (7) and the corresponding pump chamber and the pump outlet connected to the nozzle of the dispensing head according to the angular displacement of the pump rotor. The rotor is mechanically connected to an actuating mechanism (3) configured to be manually operable to release or drive the pump rotor to dispense fluid, or to block the pump rotor to stop dispensing fluid.

Description

technical field [0001] The present invention relates to a mechanical dispensing system for dispensing fluids. Background technique [0002] There are generally two types of dispensing systems, pressurized and non-pressurized. In a pressurized system, the container is filled with a gas under pressure, which is either mixed with the liquid to be dispensed or separated from it by a bag containing the liquid or gel contained within the pressure-resistant container, The bag is connected to an outlet valve and pressurized gas surrounds the bag within the container. Liquid is dispensed through an actuated valve. A disadvantage of a pressurized system is the need for a container sufficiently pressure-resistant to withstand the pressure of the propellant. Additionally, the use of volatile propellants such as butane is not environmentally friendly and is hazardous in view of its flammability. Due to technical limitations, the nature of the receivers that can be used in pressurized...
