Abstract: A one-touch high-pressure fluid fitting using a spring, in which the spring is used to press a sealing ring and simultaneously elastically support an inward inclined surface of a fitting cap, and the fitting cap is expanded upon unfastening so as to maintain an internal airtightness of a fitting body and allow a detachable structure between the fitting body and the fitting cap to be smoothly implemented.

Abstract: The present invention relates to an electric grease barrel pump that has a single pumping structure and has an automatic shift function performed by a manual operation of a valve for switching a grease supply line. The electric grease barrel pump comprises: a pumping means; a driving means; a supply pipe through which the grease is discharged from the pumping means; a distribution valve installed at an end of the supply pipe in a direction in which the grease is discharged; a magnetic switch, installed at a movable portion of the distribution valve, for outputting a signal for supplying the grease to a selected grease supply target of the plurality of grease supply targets according to an operating position of the movable portion; and a control unit for controlling the driving means to adjust grease discharge capability of the pumping means according to the signal of the magnetic switch.

Abstract: The present invention relates to a grease injection nipple coupled to a grease pipe such that the same can function as an opening/closing valve with regard to the corresponding grease pipe, the grease injection nipple being pushed against a nipple of a grease supply target and coupled thereto or separated therefrom. The grease injection nipple according to the present invention comprises a push body, a check valve, a nipple coupling portion, and a valve activation portion. The valve activation portion may operate such that, when the push body makes a primary movement in the forward direction, the check valve is opened and, when the push body makes a secondary movement in the forward direction after external force for the primary movement of the push body is released, the check valve is closed.

Abstract: The present invention relates to an electric grease barrel pump and, more particularly, to an electric grease barrel pump which is configured to supply an appropriate amount of grease to an attachment connected to a distribution valve by enabling an actuator of the distribution valve to operate in conjunction with and according to a change in the number of stages of a driving means.

Abstract: A hybrid power type of an automatic grease gun includes a storage tank to store grease, a discharge part to discharge the grease from the storage tank, a drain port to drain out the grease which is discharged from the discharge part, and a power supply part to supply power to the discharge part, to supply power, which is received from moving equipment in connection with the power of the moving equipment, to a rechargeable battery as power to be charged in the rechargeable battery, to first supply the power charged in the rechargeable battery to the discharge, and to automatically and directly supply the power of the moving equipment to the discharge part when the rechargeable battery is fully discharged.
