The invention relates to dispensers, in particular to dispensers for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source and dispensers comprising dosage counters. The invention therefore provides a dispenser for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source (C), the dispenser comprising a body for receiving a substance source, the body having a mouthpiece； a junction member slideably arranged in the body for movement in a longitudinal axis of the body to release a dose of a substance from a substance source, the junction member comprising a socket for receiving a spout of a substance source； a dispenser driver (A) for moving the junction member in the longitudinal axis of the body to release a dose of a substance from a substance source, the dispenser driver comprising a pivot shaft and a cam arranged on the shaft, the dispenser driver being arranged within the body such that rotation of the pivot shaft causes the cam to rotate and apply a force to the junction member so as to move the junction member in the longitudinal axis； and a cam follower slideably arranged within the body, the cam follower comprising a base and a substantially rigid protrusion extending from the base, the protrusion being arranged between the dispenser driver and the junction member such that a force applied by the cam of the dispenser driver to the protrusion causes the cam follower to slideably move in the longitudinal axis of the body and apply a force to the junction member so as to release a dose of a substance from a substance source.Изобретение относится к диспенсерам, в частности к диспенсерам для выдачи дозы газообразного, взвешенного в газе или имеющего форму капель вещества из источника вещества, и содержащим счетчики доз. Согласно изобретению предлагается диспенсер для выдачи дозы газообразного, взвешенного в газе или имеющего форму капель вещества из источника (C) вещества, содержащее корпус для приема
