摘要:
Plastic bottles as well as other hollow bodies are given thin functional layers by means of high vacuum coating devices. The relevant process takes place in high vacuum. The bottles to be coated as well as the coated bottles are inserted into a high vacuum chamber (20) through a sluice, which consists of carrousel drum unit. Due to the difference of pressure in the atmosphere and the high vacuum chamber, carrousel within the drum suffers a displacement or tipping, which makes the sealing of the carrousel with respect to the drum difficult. Hence the invention proposes a sluice system consisting of two sluices (23, 25) of the mentioned type, which are connected with one another by means of an intermediate vacuum chamber (22). It is thus achieved that the load due to the pressure on each drum (3) decreases, so that each sluice (23, 25) functions with lesser tendency to develop faults.

摘要:
A multistage lock chamber device with at least two lock chambers, a first pump set for evacuating a first lock chamber, and a second pump set for evacuating a second lock chamber. The first pump set (P1) may evacuate both the first and the second lock chamber, or both jointly. The first pump set may also be utilized as a prior pumping stand of the second pump set. Additionally, an integrated third pump set can be utilized as a pre-pumping stand for the second pump set and/or first pump set. Alternately or additionally, the device can include at least one buffer unit, whose buffer volume is being utilized to produce a sudden decline in pressure inside the lock chamber by means of pressure equalization.
