Definitions

  • Yet a further object of the invention resides in the provision of means conducive to a very compact and eflicacious control system of the aforesaid type, in which a predetermined pressure (low pressure, overpressure and like working conditions) influences or regulates the operation of an electric switch system which is operatively connected to a power source or aggregate.
  • a predetermined pressure low pressure, overpressure and like working conditions
  • the problem underlying the invention is to provide means devising a spark ignition device devoid of rotating parts, which problem is solved by the provision of movable parts of a circuit breaker, which parts are controlled by the pulses produced by an internal combustion engine in the gas-conducting ducts thereof. These pulses may be derived from the suction line as well as from the exhaust line of the engine.
  • a membrane box or housing is connected to a branch of the exhaust gas conducting line, the membrane contained in said bOX being exposed to the influences of pulsating gases and cooperating With the movable part of the interrupter or circuit breaker.
  • the counter contact for the circuit breaker may be disposed in a manner known per se.
  • a membrane a check valve or like device may be provided, whereby the valve plate is equipped with a movable contact part pertaining to the circuit breaker.
  • the movably arranged contact parts or carriers of the circuit breaker may be connected with the housing part and thereby readily grounded.
  • FIG. 1 shows, schematically and in section, an arrangement of a membrane-controlled circuit breaker and a circuit diagram connected therewith;
  • FIG. 2 shows a view similar to that of FIG. 1, whereby the membrane-controlled circuit breaker is replaced by a valve-controlled interrupter.
  • FIG. 1 a branch connection 1a connected to the exhaust gas line 1 of a combustion engine (not shown).
  • Membrane member 2a carries centrally thereof a movable contact element 3 which is located opposite and normally in spaced relation to the counter contact element Sax seated on the upper housing part 2b.
  • the upper housing part 2b is made from electrically non-conductive material, for example, plastic or plastic composition.
  • the membrane member 2a consists of a thin sheet material assuming a bellows form and responding to vibrations of a controlled stream of exhaust gas entering through an opening 1c of nozzle 1b, thereby flowing in the direction according to arrow A for actuation of membrane member 2a for closing contacts 3, 3a.
  • the interrupter counter contact 3a establishes then across the movable contact 3 a connection via the conductive membrane disk or member 2a and the lower part of the housing 2, which, in turn, is grounded by the branch part In of the exhaust.
  • a similar control arrangement or device is constituted by the circuit breaker construction of FIG. 2. As here shown, instead of a membrane, there is provided a check valve 6 having a valve plate 6c which applies under pressure of spring 6a against an open work support element 6b.
  • This element carries the movable circuit breaker contact 3'.
  • the counter contact 3" is held by an insulating screw arrangement 7 which is made of plastic or plastic composition and hence is separated from the ground contacting parts of check valve 6, while the movable contact 3 is grounded across spring 6a.
  • pulses emanating from the exhaust or like gas conduit 1 are communicated via branch 1a in accordance with the arrows to the valve place 6c in a manner similar to membrane member 20, as hereinabove stated with respect to FIG. 1.
  • a switch control arrangement for operating an electric circuit for the spark plug ignition of a power aggregate equipped with a conduit for fluid flow; a housing, means responsive to fluid pressure and including a displaceable member located in said housing and in communication with said conduit, and circuit breaker means in said ignition circuit for opening and closing the same, respectively, said breaker means including two cooperable contacts, respectively, supported in said housing, one of said contacts being movable to and fro the other contact and being operatively connected with said displaceable member, the other of said contacts being stationary and carried by a part of said housing, which is electrically insulated from the remainder of said housing.
  • An interrupter switch for the electrical spark ignition of a device having an exhaust gas conduit with a pulsating exhaust gas flow therethrough during operation of the device comprising a closed housing, an extension conduit connected into the lower end of said housing and into said exhaust gas conduit, a member extending across said extension conduit adjacent the connection to said exhaust gasconduit and having an orifice opening therethrough, a movable member disposed across said housing exposed to the pulsating gas flow from said extension conduit, a spark ignition circuit, a first contact connected in said spark ignition circuit and mounted in a fixed location in said housing on a side thereof opposite from said extension conduit, and a second contact connected in said spark ignition circuit carried by said movable member on the same side of said housing as said first contact and being displaceable with said movable member into and out of engagement with said first contact in accordance with the pulsating gas flow in said conduit.
