ENGINE STARTER ARRANGEMENT
The present invention relates to improvements in the
construction of starters for starting internal combustion 10
engines.
The starters of the present invention may be con
structed in the most convenient size and form for each
case, and, especially in the smaller power types of starter,
they may be of cylindrical form, similar to electrical auto
mobile starters. Notwithstanding the facts that the starter
is of great power and is ‘free from the weaknesses of elec
trical motors, said starter is of relatively small size as
compared with its great power.
In order that the present invention may be readily car
ried into effect, it will now be described with reference to
valve‘housing so that ?uid in the area of the head end
?ow between said piston type valve head and said valve
auxiliary valve 3 also comprises an auxiliary valve seat
10 at its ‘head end and an auxiliary valve spring 11 which
is positioned inside or under the piston type auxiliary
valve head 8 in a manner whereby it controls the move
ment of said valve head jointly with the pressure of the
?uid.
When the starter valve 2 is opened by the pressing of
its push button 1'2, the ?uid in a third conduit 13 and
under the auxiliary valve head 8 is released to the atmos—
phere. The ?uid pressure in the second conduit 6 on
the upper surface of the auxiliary valve head 8 over
comes the bias of the auxiliary valve spring 11 and opens
the auxiliary valve 3. This permits ?uid to ?ow through
the ?rst conduit 4 and a fourth conduit 14 to a motor
feeding ?fth conduit 15 and to the area of the lower part
