Abstract: The invention relates to a method of draining condensate from a reservoir that communicates with a trap via a drain pipe. The reservoir is subjected to a gas pressure p(reservoir) that can be below atmospheric pressure p(air) or above atmospheric pressure p(air). The method involves the following steps: a) collecting condensate in the reservoir, b) acquiring the fill level by means of a level meter, c) providing a control pressure p(control) which, in any operating conditions of the compressed gas system, is above the pressure p(reservoir) in the reservoir and above atmospheric pressure p(air), d) providing, under control, a control conduit input of an exhaust valve, which is assigned to the reservoir and is intended to drain the condensate collected in the reservoir, with a pressure p(input).

Abstract: The dryer for compressed air comprises a filter bowl (20), which has an inlet (22) for damp compressed air, an outlet (24) for dried compressed air, a scavenging air inlet (26) and a scavenging air outlet (28). A membrane is accommodated in the filter bowl (20). The membrane lets selectively water steam flow through and has two sides. One side of the membrane is stroked by the compressed air, while scavenging air flows on the other side of the membrane. A feeder pipe (32) is provided, through which dried compressed air coming from the outlet (24) is fed into the scavenging air inlet (26). A closing device (34, 36, 38) is arranged in the feeder pipe (32) and has a closed position. The closed position depends on the consumption of compressed air in such a way that more or less scavenging air is made available when more or less compressed air is taken by a consumer device, operated by dried compressed air.

Abstract: A method for draining condensate off a compressed-gas system that traps condensate that collects during operation of the compressed-gas system, draws off collected condensate through an outlet, connects a trap volume and a purging device to the outlet, connects a collection chamber to the outlet, detects the presence of condensate in the collection chamber by at least one sensor, connects control electronics to the sensor, controls a valve arrangement by the control electronics that either shuts the purging device so that no condensate can escape through it or opens the purging device each time the condensate level rises and the sensor changes over from indicating “no condensate” to indicating “condensate present”, starts the timer circuit and on expiry of the time defined by the timer circuit, opens the valve until the sensor indicates “no condensate” thereupon closing the purging device with the valve.

Abstract: The present invention relates to a device for removing condensate from gas pressure systems, especially dry-pipe systems having a condensate collector in which condensate accumulates when the gas pressure system is in operation, the collector being provided with an outlet. The collector also has a gauge containing a tubular body which is sized in relation to the outlet and designed to be secured thereto and which, when mounted, is located inside the collector and includes an electronic sensor, preferably a capacitive sensor, which is supported by the tubular body and of which at least one element, i.e., a preamplifier, is located therein and borne thereby, and is capable of functioning as a control for an external valve system.

Abstract: A one-piece or multi-part connecting rod includes a connecting rod eye, connecting rod shaft and a connecting rod head which is manufactured from at least one sheet metal strip. The sheet metal strip is shaped on both sides with essentially perpendicular fins and is bent normal to its main planed formed cylindrical or semi-cylindrical bearing surfaces about the bearing axes of the connecting rod head and connecting rod eye. The sheet metal pieces are fastenable near the bearing surfaces. The sheet metal connecting rods thus produced can be moved in automobile engines.

Abstract: Apparatus for cold drying or cold-condensing of gas comprises a heat exchange device and drying device through which a cold-carrying medium flows and which is cooled to such an extent that moisture contained in the gas under treatment is condensed out, frosted out, frozen out and/or liquefied. The heat exchange device and the drying device comprise an integral unit. At least one discharge pipe drains away the liquid condensate, the frost or ice and/or the liquid which are separated from the gas flow.

Abstract: An arrangement is disclosed for the separation of floating oil from oil/water mixtures, in which the arrangement comprises a tank which contains the mixture, at least one inlet for the mixture and separate outlets for the floating oil and the remaining liquid mixture. In addition, three sensors are provided which are arranged on the tank so as to be vertically displaced relative to each other. The sensors which are arranged uppermost and in the middle control the discharge means for the floating oil, while the sensors arranged in the middle and lowermost are designed and provided to control the discharge means for the liquid mixture to an emulsion separator.

Abstract: A device is disclosed to measure the level of material within containers, in particular containers in which free-flowing materials having different dielectric constants, for example water and oil, are collected. The device includes a sensor, which is arranged electrically nonconductively fashion on an outer side of the container and forms part of an electric capacitor, and an electrically conducting complementary plate, which is arranged on the inside of container opposite the sensor and spaced therefrom, which, forms another part of an electric capacitor.

Abstract: In a so-called condensate trap for discharging condensate, e.g. oil or water from a fluid system which contains air or a gas or vapor under pressure, a single tube which projects into a housing in which the condensate collects contains spaced sensors of an electric capacitive type sensing the maximum level which the condensate is to be allowed to reach within the chamber and a predetermined lower level. A signal from the upper sensor triggers a pilot valve which opens a diaphragm-type discharge valve and a signal from the lower sensor initiates closing of the valve, but only after a time delay, allowing the condensate to fall first to a level below that of the lower sensor. This time delay is related to the time taken for the condensate to fall from the maximum level to that of the lower sensor. The control unit and sensor tube form a self-contained structural assembly for easy installation and replacement.
