Injection Oilers, Micro umps Injection oiler with counting stage (reduction) The injection oilers described on the preceding pages deliver the set amount of oil every time they are actuated. Injection oiler with counting stage, order No. 501-301-400 ~60 If the delivery rate is much too high, despite selection of the right actuating valve, the feed can be reduced to between 1/10 and 1/50 with the help of an injection oiler with counting stage. 56 72 6 M6 0.75 501-301-400 b c If a number of normal injection oilers are to be installed downstream from this unit, the entire group will deliver in accordance with the reduction ratio set. Design Two chambers of the 3-way housing are used to reduce the rate, thus leaving only one outlet available. Input stage a, actuated by the pressure pulse, does not deliver directly to the lubrication point but to counting stage c (piston accumulator). When the cavity is full, a valve is opened that directs the pilot air to delivery stage b and to any injection oilers downstream from the stage. These injection oilers, for their part, now deliver in the same reduction ratio the volume of oil individually set with each setting sleeve. The reduction ratio is determined with the setting sleeve of input stage a. left stop, reduction ratio = 10 : 1 right stop, reduction ratio = 50 : 1 The quantity of oil intended for the lubrication point is determined with the setting sleeves of delivery stage b. The accumulator piston is reset automatically. The unit works until the pilot air pulses arrive.
