' the yparts normally occupy the position .illus` trate'd in Fig. 1,'in which the piston ,is posi,- tioned between the port 15 and the two ports 16V and 17 which in consequence are all unfA cove-red, the-'

electrodes

8 and 10 aresepa-v rated, the valve-23-closes the exhaustport 17, the admission port 16 is uncoveredvby the valve 22 and the'solenoid27'1is dener,` git/led. The parts are held in. this position by-- the action o the spring 28 until the' compression of thecharge'in the cylinder 2 causes' a portion ofthe compressed gases to 'enter theY part of the piston chamber behind-the piston along a course which includes the openings 9, the interior of the member-6, the passage -21the valvechamber 18 and the admission l so.
