The suction valve yA3 opens downwards on the suction stroke, delivering the gas direct into the cylinder and the delivery valves Bf open upwards on the compression stroke the gas being delivered from the cylinder -C through t e annular space or slot c between the cylinder body and the cylinder head, to the delivery passage F and outlet pipe F1.
In the construction shown in Figs. 1l .to 14 the suction valvesA are disposed inl a circle opening downwards fitted into recesses a in 'the end of the cylinder bodyl and held against their seats by springs a1. The delivery valve comprises a concentric ring ot' four ball valves B held to their seats yby springs b1 and the suction passages E and delivery passages F are formed in the cylinder head D and connect with corresponding passages inthe cylinder body to which the inlet pipe E1 and outlet pipe F1 are connected the arrangement and disposition of the valves and passages being very similar to those shown in Figs. 2 and 3. Between Vmulti-cylinder machines.
Aing in the cylinder end the body of the cylinder C and the cylinder head D a valve seating plate H is inserted in which seating valves are formed,with the object of obtaining valve where sound castings are difficult to obtain. The plate H forms the bottom of the annular suction passage E and the gas delivery passage F thus enabling the cast iron cylinder head D to be made without closed cored passages.. The valve seating plate H may be made with several sets of seatings for The partly annular suction passage E is interrupted at k where the gas delivery passage F passed across the same plane. In the arrangement shown there are two suction-passages e passing upwards through the valveseating plate H andone delivery passage f. For simplicity in machining the suction passage e and delivery passage j through the valve seating plate H are bored circular instead of being cast triangular as in Fig. 2. If the valve plate H is made or' cast metal the suction and delivery passages e and f therein may be cast triangular or of other suitable shape.
