A valve-type oil feeder comprising a housing, a valving spindle, and a piston. The housing has a valve chamber and a piston chamber, the valve chamber has an oil inlet, a first outlet, and a second outlet; the piston chamber has an oil intake chamber, an oil discharge chamber, and an oil outlet; the oil intake chamber communicates with the second outlet, and the oil discharge chamber communicates with the first outlet and the oil outlet respectively; the valving spindle is arranged in the valve chamber and movable between an original position at which the oil inlet is cut off from the second outlet while the first outlet communicates with the second outlet, and a working position at which the oil inlet communicates with the second outlet while the first outlet is cut off from the second outlet The present invention is applicable to various fluid and semi-fluid media, and applicable to various pressure and viscosity ranges. By controlling the operation of the valving spindle, lubricant can be supplied conveniently as necessary, and the delivery quantity of lubricant can be adjusted easily; moreover, the valve-type oil feeder is characterized in simple structure, wide application range, low production cost, and reliable operation.
