A power train for vehicles having a swashplate type continuously variable transmission having a swashplate hydraulic pump and a swashplate hydraulic motor, a transmission cylinder therebetween with a plurality of pump plunger holes and motor plunger holes formed therein. The transmission cylinder is rotatable about an axis and is coupled with the crankshaft of the engine. The pump swashplate is rotatable and disposed at an angle to the axis of the transmission cylinder and is coupled with pump plungers. A motor swashplate which is variably inclined relative to the axis of the cylinder and includes motor plungers associated with the cylinder. The swashplates have a number of spherical protruding portions which are abutted by spherical concave portions on the plungers with the concavities having a larger radius of curvature than the protruding portions with engagement varying from radially outwardly to radially inwardly of the axes of the plungers relative to the cylinder and radial forces are diametrically disposed to center the swashplate.

Swashplate assembly for a swashplate type hydraulic pressure device

A secondary air introducing device for an engine including a cylinder, an associated piston, and a secondary air introducing hole formed in a side wall of the cylinder in such a manner that said hole is located near the bottom dead center of the piston and is opened and closed by the piston. The secondary air introducing hole is made to communicates through inlet passages with the atmosphere, so that the external air is introduced into the cylinder through the secondary air introducing hole by a negative pressure which is produced in the cylinder at the end of a suction stroke of said engine, and a control valve means opened and closed according to variations in load of the engine is provided in the inlet passages, thus controlling an amount of air introduced therein.

Secondary air introducing device in engine

A secondary air introducing apparatus for an internal combustion engine comprising a secondary air introducing opening in the sidewall of the cylinder near the position of lower dead point of a piston of the engine. The opening is opened and closed by the piston. A secondary air supply source is interconnected with the opening by an introducing passage. The introducing passage is formed to be an upwardly directed passage extending only upwards from the opening.
