Abstract
281,893. Leach, R. W. Jan. 25, 1927. Force-feed lubricating.-In rotatable plug cocks or valves, relatively large distributing-passages c communicating with the surface through narrow slits d or perforations are provided in combination with a stepped groove or grooves k in the casing communicating with the passages for the supply of lubricant thereto. The lubricant is supplied under pressure from a chamber e containing a piston f actuated by a spring g or by the pressure of the fluid being conveyed. From the chamber e an axial bore h, preferably provided with a non-return valve i, leads to a transverse passage j in the plug, communicating with the stepped groove k. The ends c<1> of the distributing-passages c or of the transverse passage i are so arranged in relation to the stepped groove k that communication is interrupted during periods in the operation of the valve when the orifices d are exposed to the fluid being conveyed. In a modification, the stepped groove k communicates directly with the chamber e, which may be arranged in the plug. The passages c are in communication at their upper ends by an annular groove m which may also be stepped. Specification 112,375, [Class 12 (ii), Lubricating passages &c.], is referred to.
