The structure where the linear motion plunger pump which it confronts each other opposes, with kamuhuoroa, converts the cam which turns to linear motion, incorporates the compression spring and the piston in the cylinder head, and the space inside the cylinder by compression rally of this spring, forms the positive cam which follows to the cam which turns, with crankless piston reciprocating motion, executes the air intake compressed exhaust air of the pump.

摘要

PROBLEM TO BE SOLVED: To obtain a high speed piston reciprocating stroke in a low noise cylinder intake-cylinder head exhaust structure capable of increasing an ejection amount while saving power.;SOLUTION: An inlet port at a cylinder side surface is opened and closed by the other cylinder which is a cylinder interlocked with a piston, a cylinder-head exhaust port is opened and closed by a tappet of a reciprocating piston. The high-speed reciprocating motion of the piston is carried out by the high-speed rotation of a displacement cam.;COPYRIGHT: (C)2011,JPO&INPIT
