Definitions

  • the present invention relates to a gas-developing galvanic element according to the preamble of claim 1.
  • a cylindrical rod made of molybdenum or another material forming a cathode is inserted into a central bore of a round blank made of zinc.
  • This element is exposed to an electrolyte, whereby a certain amount of gas is continuously generated by an electrochemical process on the cathode, which is used, for example, in a lubricant sleeve for the continuous ejection of a certain lubricant from a lubricant reservoir (DE-PS 1256001).
  • the area of the cathode accessible to the electrolyte determines the amount of gas generated, the environmental conditions, such as. B. the temperature, are also of influence.
  • the present invention has for its object to provide a gas-developing galvanic element in which the amount of gas generated per unit time can be adjusted and controlled regardless of the surface of the cathode exposed to the electrolyte and also the total amount of gas generated. The influence of temperature on the amount of gas per unit of time is also reduced.
  • the resistance is designed to be controllable, then different gas quantities can be generated with one and the same resistor.
  • the anode is expediently made of zinc and the cathode is made of a material with low hydrogen overvoltage. This can be nickel, Raney nickel, platinum or the like.
  • the use of zinc as an anode has the advantage that the total amount of zinc can be selected according to the desired gas quantity. When the intended amount of zinc is used up, a new zinc tablet can be arranged, i. H. so the element itself can be regenerated again.
  • the cathode can be formed in the form of a plate or a film, in many cases a coating over a correspondingly designed carrier is sufficient.
  • the only figure shows the element that consists of the anode 1 from z. B. zinc in the form of a tablet, from the cathode 2 of z. B. Raney nickel in the form of a plate and consists of the arranged between anode 1 and cathode 2 resistor 3.
  • the individual parts are interconnected. If this element is placed in an electrolyte (not shown), so that a chemical reaction occurs, whereby the zinc of the anode 1 dissolves and gas forms at the cathode 2, which collects in a room and then for example as described in the introduction to continuous ejection of lubricant or the like is used.
  • a corresponding resistor 3 is selected or set.
  • the amount of zinc of the anode 1 is selected depending on the desired amount of gas, so that each element can be adapted to the particular conditions of use.
  • the element can still be retrofitted or regenerated by renewing the zinc tablet.
  • the resistor can be attached outside the device, with appropriate connections to the cathode and anode.
