Abstract
A dual dispenser having two pumps, a first pump with a first actuating pin axially displaceable over a first maximum travel, and a second pump with a second actuating pin axially displaceable over a second maximum travel. The dispenser has a common piston axially displaceable and that acts axially and directly on the first actuating pin to drive it over its first maximum travel. The first maximum travel is greater than the second maximum travel. The dispenser includes reduced a speed transmission mechanism acting between the common piston and the second actuating pin to transmit the axial thrust force of the common piston to the second actuating pin with a reduced speed of the second actuating pin with respect to that of the first actuating pin.
Claims12
A dual dispenser comprising two pumps, namely:
- a first pump provided with a first actuating pin that is axially displaceable over a first maximum travel, and
- a second pump provided with a second actuating pin that is axially displaceable over a second maximum travel,
- the dispenser comprising a common piston that is axially displaceable and that acts axially and directly on the first actuating pin in order to drive it over its first maximum travel,
- wherein:
- the first maximum travel is greater than the second maximum travel, and
- the dispenser further comprises reduced speed transmission means acting between the common piston and the second actuating pin in order to transmit the axial thrust force of the common piston to the second actuating pin with a speed of the second actuating pin that is reduced with respect to that of the first actuating pin, the speeds of the actuating pins being different and not zero.
