<p>An oil spray device having a valve is provided to produce the oil jet device not to generate vibration and wear, to be compact by having less number of parts, and to be easy to manufacture by using parts not required for precision manufacturing processes. An oil spray device having a valve includes a main body(1), a through-hole passageway(12) in the axial direction of the main body, a tubular guide liner(4) fixed to the main body by a down stream section(4c), an upstream section(4b) separated from the wall of the through hole passageway to allow cooling medium pass through, and a valve(2) sliding in the axial passageway of the tubular guide liner and moving toward seats formed around the main body by a return spring(3).</p> |
