Abstract

In a dispenser a manually operable thrust piston pump (2) has a presuction piston (11) located with a limited spacing within a pump piston (10) and which in the manner of a telescopic tube engages over a cylindrical, freely projecting chamber body (15) and consequently bounds a presuction chamber (17) constantly connected by a line to a container and whose length and volume are significantly greater than that of a pump chamber (20) surrounding presuction chamber (17). The two working pistons slideably guided on one another form valve closures of an outlet valve (23) controlled by pressure difference and which at the end of the pump travel and in addition to said control, can be mechanically opened by a dog (40) positionally variable by means of a compressible neck (29) for venting the pump chamber (14).
