A valve system, especially for use in a veterinary syringe, comprises a valve body which is arranged in a valve space formed between a first part having a valve seat and a second part which presses the valve body against the valve seat under influence of spring force. The valve body has, in an area adjacent to the valve seat, projections which are directed radially outwardly. The valve space has, at a bore hole surface, a projection directed radially inwardly and having an inner diameter. The projections of the valve body which are directed outwardly are arranged between the valve seat and the inwardly directed projection of the valve space. The projections of the valve body and the inwardly directed projection of the valve space are constructed elastically. The inner diameter formed by the projection of the valve space is smaller than an outer diameter formed by the projections of the valve body.
