Abstract
A substance delivery apparatus, such as a spraying apparatus, that includes an adjustment element for regulating the flow of at least one substance between at least one inlet and at least one outlet. The adjustment element is displaceable between a first position, corresponding to a first delivery condition of the at least one substance, and a second position, corresponding to a second delivery condition of the at least one substance, and the adjustment element comprises at least one sealing element for facilitating airtight fluid communication in association with at least one of the first and second delivery conditions.
Claims28
A substance delivery apparatus comprising:
- at least one inlet for accepting at least one substance;
- at least one outlet for permitting delivery of said at least one substance;
- and
- an adjustment element for regulating flow of the at least one substance between said at least one inlet and said at least one outlet;
- said adjustment element being displaceable between at least a first position, corresponding to a first delivery condition of the at least one substance, and a second position, corresponding to a second delivery condition of the at least one substance;
- said adjustment element comprising at least one sealing element for facilitating airtight fluid communication in association with at least one of said first and second delivery conditions;
- said adjustment element being further displaceable to a third position, corresponding to a third delivery condition of the at least one substance;
- and
- said substance delivery apparatus further comprising a longitudinal actuator for slidably displacing said adjustment element.

- said adjustment element being displaceable between at least a first position, corresponding to a first delivery condition of the at least one substance, and a second position, corresponding to a second delivery condition of the at least one substance;
- said adjustment element comprising at least one sealing element for facilitating airtight fluid communication in association with at least one of said first and second delivery conditions;
- said adjustment element being further displaceable to a third position, corresponding to a third delivery condition of the at least one substance, and a fourth position, corresponding to a fourth delivery condition of the at least one substance;
- said at least one inlet includes a first inlet adapted to accept a first substance and a second inlet adapted to accept a second substance;
- said first delivery condition corresponds to delivery of neither of the first and second substances through said at least one outlet;
- said second delivery condition corresponds to delivery of solely the first substance through said at least one outlet;
- said third delivery condition corresponds to delivery of a mixture of the first and second substances through said at least one outlet in accordance with a first ratio of the first and second substances with respect to one another;
- and
- said fourth delivery condition corresponds to delivery of a mixture of the first and second substances through said at least one outlet in accordance with a second ratio of the first and second substances with respect to one another, the second ratio being different from the first ratio.
