Piston is affected.

Patented in the German Empire on August 27, 1912.

The subject of the invention forms a pressure surge gas remote igniter, in which a Switching mechanism for opening and closing the gas seal moved by a piston will. A remote detonator of this type is already known. With this a valve closes, its effective area in relation to that which comes into effect after lifting Piston area is very small, gas admission

ίο to the piston. As a result of for the easy Mobility not tight guidance of the piston can with the known remote detonator Gas will escape in the raised position of the piston. To prevent this and

is easy even with a slight increase in pressure To create a liftable piston, according to the invention, the piston is in the rest position only with its outer ring surface on one is directly on the inner surface of the

äo container adjoining sealing ring and hits a sealing ring in the raised position.

In the drawing, a gas remote igniter designed in accordance with the invention is exemplified

ä5 shown, namely shows:

Fig. Ι a vertical section through the gas with the closure plate removed, and

Fig. 2 shows a longitudinal section through this.

The gas remote igniter consists of a housing a, which is connected to the gas line b and in which a ratchet wheel e is arranged, which is indexed by a ratchet d when the gas pressure increases, while a second ratchet e holds the ratchet wheel c in the new position . A spring f rests against the ratchet wheel (FIG. 2), which prevents the ratchet wheel from moving further than a tooth. This ensures that the rear derailleur can never get out of order. A ratchet wheel g is connected to ratchet wheel c , on which valve rod h of valve cone i rests, so that when wheel g is switched, the valve is opened at the first pressure surge, kept open at the second pressure surge and closed with the third pressure surge. The remote igniter shown is therefore used for night flames. which burn beyond the usual time. For evening flames, the ratchet wheels must be set up in such a way that the ratchet wheel g has half as many teeth as the ratchet wheel c.

An angle lever / is connected to the pawl d , to which a rod k is articulated, which passes through the bore I of a container m arranged outside the housing h and is articulated to a piston η which is arranged in the container m so that it can move easily . In the normal position, the piston η sits with its outer circumferential surface on a sealing surface 0 directly adjoining the inner surface of the container m , onto which it is ground so that gas around the piston cannot escape. A rod p is located in the center of the piston.

arranges which can be loaded accordingly by weights q. The container is closed by a lid r . Above the piston η , a ring s is also inserted into the container m , which ring is held in position by a ring t. The ring s is used to seal the upper piston part when the piston is raised, for which purpose the upper piston part on the ring s

ίο is sanded up.

The remote igniter is illustrated in the drawing for use with a single flame, However, it can also be used for double flames and is in this Trap provided with double derailleur, which is from a common drive is operated. The remote detonator is also suitable for both standing and hanging Suitable for incandescent gas; in the latter case, however, the inlet and outlet of the gas must be changed accordingly.

Claims (1)

Patent claim: Pressure surge gas remote igniter, in which 2; the switching mechanism is influenced by an easily movable piston, characterized in that the piston (ή) in the rest position rests with its outer ring surface on a sealing ring (0) directly adjoining the inner surface of the container (m) and in the raised position hits against a sealing ring (s). 1 sheet of drawings.
