The invention relates to a dispenser (1) for pasty compounds (M), comprising a tubular compound housing (2) having a feeding plunger (7) and a head piece (3) which is guided in a spring-mounted manner on the upper tube piece (9) and has a metering chamber (18) with which there is associated an inlet valve (35). In order to provide a dispenser of this kind that has improved performance and a simplified construction, it is proposed that the spring element (25) is composed of two U legs (28, 29) which roll down between parallel annular walls (16, 32) of the head piece (3) and the compound housing (2). |
