A pair of annular coil units for a stepping motor in which each of the coil units has three coil terminals and the ends of the lead wires connected thereto encapsulated by a synthetic resin thereby forming outwardly extending projections. Recesses are found between the projections so that the lead wires of one of the coil units can be laid out in the recesses between the terminals of the other coil unit.

Lead wire layout in coil units for stepping motor

A flow rate control valve system in which a valve plug is linearly driven against a valve seat by a stepping motor. The valve plug is fixed to a sleeve that has internal threads mating with external threads on the motor shaft. Splines prevent rotation of sleeve and plug. Two closely fitted cylinders are respectively supported by the motor housing and the valve plug.

Flow rate control valve system

A flow rate control valve system in which a valve plug is linearly driven against a valve seat by a stepping motor. The valve plug is fixed to a sleeve that has internal threads mating with external threads on the motor shaft. Splines prevent rotation of sleeve and plug. A bearing is interposed between a smooth end of the shaft and the plug.

The opposite end flanges 1d, 1e of a stator bobbin are provided with apertures 1a, 1b and clamping recesses 1c to firmly retain push-inserted terminal plates 3 and lead wires 4 during encapsulation by a molding resin 5. The retention of the terminal plate ends is implemented by spring flukes 3c snapping into engagement with flange apertures 1b during insertion.

Connection terminal assembly for stator coil

A combustion apparatus for a vehicle for regenerating a filter provided in an exhaust gas passage of an engine by burning and removing fine particles in the exhaust gas comprising an air supply passage for coaxially supplying air along the outer periphery of a fuel injection nozzle, a shut-off valve mounted at the downstream side end of said combustion chamber for preventing reverse flow of the exhaust gas, and a controller for allowing the inflow of the coaxial air for a predetermined period of time after stopping the fuel supply from the fuel injection nozzle and then closing the shut-off valve.
