    Abstract: A dosing valve for liquid or pasty products includes a hollow valve body with an inner chamber, a normally open inlet communicating with a recipient of a product, and an outlet normally closed by a spring-urged clapper. Part of the body can be elastically deformed to reduce the volume of the chamber and compress the product therein to close the inlet, open the outlet and deliver a discrete dose of the product.

    Abstract: A dosing valve for liquid product comprises a valve body open in the upper part to receive product and having an outlet orifice at the lower part. An upper disc is displacable above a pierced separating member in a cylindrical housing in the body, the disc being smaller than the housing to leave a gap for the passage of product. The upper disc is displacable, against the action of a spring, from an upper position in which it allows passage of a dose of product towards a lower position in which it stops the passage of product. A lower disc, for controlling the passage of doses of product through the separating member to the outlet orifice, is normally applied against the lower face of the separating member by the difference in the atmospheric pressure acting downstream of the lower disc and a depression created upstream of the lower disc when the upper disc moves from the lower position to the upper position.

    Abstract translation: 用于液体产品的计量阀包括在上部开口以接收产品并在下部具有出口孔的阀体。 上盘在身体中的圆柱形壳体中的穿孔分离构件上方可置换，盘比壳体小以留出用于产品通过的间隙。 上盘可以从弹簧的作用移动，从上部位置，其中允许剂量的产品向下停止产品通过的下部位置。 用于控制通过分离构件到出口孔的产品剂量通过的下盘通常通过作用在下盘下游的大气压差和上游产生的凹陷而抵靠分离构件的下表面施加 当上盘从下位置移动到上位置时，
