SPINNING SYSTEM - DESCRIPTION AND OPERATION
1. GENERAL
To perform the engine spinning at starting, use is made of the compressed air distributor, starting valves and
fuel priming system.
The compressed air distributor automatically distributes compressed air among the cylinders at power stroke
thus rotating the crankshaft.
The fittings for supply of compressed air to the cylinders comprise nine connecting pipes and nine starting
valves screwed into the head of each cylinder.
The fuel priming system serves to enrich the working mixture to facilitate starting. 2. CONSTRUCTION
2.1. COMPRESSED AIR DISTRIBUTOR
The compressed air distributor comprises a housing, cover, drive shaft, slide valve, elbow, pad, thrust
bearing, adjustment coupling, nine connections, ball valve and other parts.
Housing (12) (Ref. Fig. 1) and cover (7) are made of aluminium alloy and are interconnected by three studs
(9). Bronze pad (11) supporting steel thrust bearing (17) is installed between the housing and the cover. The joints
between the housing, pad and cover are sealed with paronite gaskets (18) and (19).
Bronze bushings (3) and (15) are pressed inside the housing and. cover. The cover has plug (1) sealed with
gasket (2).
The compressed air distributor is rotated by a driven gear of the drive, made integral with shaft (14). The
splined end of shaft (14) imparts rotation through adjustment coupling (16) having external and internal splines to
thrust bearing (17) with end projection rotating slide valve (6).
The disk of slide valve (6) is constantly pressed by compression spring (10) to bushing (3) of cover (7) and
by-passes compressed air through two ports positioned at different distances from the center for starting the engine
or scavenging lower cylinders,
Compressed air is fed to the cylinders for starting the engine through the port adjacent to the slide valve
center and through all the holes in the distributor cover.
