| 摘要 |
The invention relates to a device for distributing and dosing pasty, liquid, semi-liquid or pulverulent products. The inventive device comprises a valve body (1) which is provided with a through channel (2) for moving the product from a feed opening (3) to a delivery nozzle (4) in dosed quantities. A valve seat (5) is formed in the channel (2) and a valve (6) is mounted in said channel. The device is essentially characterised in that the product through channel (2) comprises a rectilinear product passage segment in which the valve seat is disposed and in which the valve (6) and the valve rod (7) extend axially and in full. Moreover, the valve drive mechanism penetrates said product passage segment at least in part. The drive mechanism is in contact with the product such that the mechanical link between the valve rod (7) and the drive mechanism is also in contact with the product and is lubricated by said product.
