Description

Dispenser for liquids, particularly lubricating oils. The invention relates to a device for evenly dispensing liquids, in particular Lubricating oils, which also change the flow work when the temperature changes, and exists from a dispensing container to which the liquid is supplied in excess, with a adjustable outlet opening. Such facilities again show a height after adjustable overflow opening. Many fluids, especially lubricating oils, have now a more sluggish flow work with falling temperatures. This would turn out to be significantly reduce a number of drops set at a higher temperature, namely as the cooling progresses.

In order to dispense the same quantity at falling temperatures as at higher temperatures To obtain degrees of warmth, the invention consists in a device which is automatic results in a different level of liquid within the device. Through this one achieves that with warmer and therefore easily flowable contents a lower one The liquid level is present at a certain pressure at the delivery point is equivalent to.

If the temperature of the liquid falls, the lower overflow is sufficient no longer for the fluid, which has become more rigid, to cross over. The cattle rises more Liquid higher, finding more overflows. So the more rigid the liquid the more transfer openings are required so that the transfer to Drain point can take place.

Due to the automatically resulting higher liquid level at the same time the pressure at the delivery point increases, so that the otherwise sluggish Levy is avoided.

The invention is illustrated in exemplary embodiments, namely show Figs. i to 3 sections through such arrangements.

In the housing i of Fig. I, a spindle 2, adjustable by thread 6, dips into the container bore 3, the cone q of which. can regulate the size of the passage opening to the outlet channel 5. From a container or a pump line, the liquid passes in excess at 7 into the channel 8, which is in open connection with the container 3. In the right wall of the channel 8 overflows 12 to 12 "1" are attached, through which the excess amount can drain into the drain 9 and from here into the container ii.

As the temperature drops, the oil becomes thicker and therefore drips off more slowly. Since, however, at the same time the transition to the bore 9 is more sluggish, the oil level in the bore 8 rises correspondingly higher, whereby the higher bores come into use depending on the increase. The higher oil level now leads to a higher pressure, so that at the throttle point q. ' a higher pressure occurs. The oil level in Fig. 2 corresponds to the cooled oil, whereby the bores 12, 12 'and 12 " are active for overflow. If the oil becomes warmer and therefore more fluid, the oil level drops accordingly, whereby the fluid pressure at ¢ also drops.

By choosing the holes 12 to 1z "" and their distances from one another, the variable viscosity can be taken into account, see above that the fluid pressure changes as the temperatures change.

In Fig. 2, the crossings are placed in a pipe. This Pipe is connected to the drip pipe io '. This pipe can be known in Way be arranged interchangeably. Instead of the bores, the overflow can be used through slots 12a (Fig. 3).

Claims (2)

PATENT CLAIM: i. Dispensing containers, especially for lubricants, which is supplied in excess, with a controllable outlet and a height-adjustable overflow in the container, characterized by several in different heights one above the other, arranged overflows to regulate the liquid level in the dispensing container and thus the outlet according to the temperatures. 2. Device according to claim i, characterized by overflows in the form of in the longitudinal direction of the container extending slots.
