Abstract: A high-pressure cutting fluid guide apparatus of a turret head of a machine tool is provided. When a high-pressure cutting fluid is input to a cutting liquid passage, the high-pressure cutting fluid flows along a through hole of a water guide cylinder, and passes through a main perforation of a partition, and then flows to a water outlet of a sealing ring to be guided into a water inlet of a cutting disc. A secondary perforation of the partition guides the high-pressure cutting fluid in the through hole to a press surface portion of the sealing ring. The sealing ring is located in an annular trough, and the press surface portion is pushed by the high-pressure cutting fluid pressure to generate the energy of the axial displacement.

Abstract: An output shaft lubricating structure of a liquid pressurizing pump is provided. A first eccentric portion of an output shaft acts as the maximum stress for load when the liquid is pressurized and works. By the power of the output shaft, a telescopic piston of an oil supply device is directly pushed by a second eccentric portion to draw the lubricating oil in a circular core hole and to pressurize and supply the lubricating oil to an oil supply hole of the output shaft to force an oil outlet hole to drain the lubricating oil to the surface of the first eccentric portion for circulatory supplement, such that the turning of a turning wheel on the first eccentric portion can keep better lubrication for a long time so as to prolong the service life of the output shaft and the turning wheel.

Abstract: A pump includes a cylindrical main body comprising a central channel, four valve assemblies each threadedly fastened in a radial hole, first and second cavities disposed to each hole and communicating therewith, a spring activated first check valve in each first cavity, a spring activated second check valve in each second cavity, an outlet, a threaded outlet orifice communicating with the outlet, an inlet, a threaded inlet orifice communicating with the inlet, four plungers each in a plunger chamber communicating between the hole and the channel, opposite outlet and inlet tunnels, two snapping members each having a central hole and a snapping bifurcation at either bent end, the snapping bifurcation slidably put on an end of the plunger; a top cover; a bottom cover; and an eccentric shaft having one end secured to motor shaft and other portions in the main body to operatively secure to the snapping members.
