Abstract
Abstract The invention relates to a cable cleaning and lubricating system comprising a chamber (5) adapted to surround a section of a cable (4) to be cleaned and to be displaced relative to the cable (4), nozzles (7) within the chamber (5) for directing jets of relatively high pressure cleaning liquid onto the surface of the cable (4), sealing means (6) at both ends of the chamber (5) and adapted to contact the cable (4), the chamber (5) being provided with an outlet (10) which is in communication with a vacuum pump for reducing the pressure in the chamber (5) to a value below atmospheric pressure. The invention relates furthermore to the use of this system for cleaning and lubricating a cable (FIG. 1).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
207 words
A method of cleaning and lubricating a cable by means of a cable cleaning and lubricating system of the type which includes a chamber adapted to surround a section of a cable to be cleaned and lubricated and to be displaced relative to the cable, nozzles within the chamber for directing jets of relatively high pressure cleaning and lubricating liquid onto the surface of the cable, sealing means at both ends of the chamber and adapted to contact the cable, and the chamber being provided with an outlet, which method comprises: displacing the chamber relative to the cable, passing the cleaning and lubricating liquid at a relatively high pressure to the nozzles in order to direct jets of relatively high pressure liquid onto the surface of the cable, operating a vacuum pump in communication with a vapor space of a tank for collecting used cleaning liquid and with the outlet of the chamber so as to cause a reduction of pressure in the vapor space and in the chamber to a value which is so much below atmospheric pressure that a flow of air from the surroundings along the sealing means and into the chamber is maintained, whereby any leakage of fluid from the chamber is prevented.

A method of cleaning and lubricating a cable by means of a cable cleaning and lubricating system of the type which includes a chamber adapted to surround a section of a cable to be cleaned and lubricated and to be displaced relative to the cable, nozzles within the chamber for directing jets of relatively high pressure cleaning and lubricating liquid onto the surface of the cable, sealing means at both ends of the chamber and adapted to contact the cable, and the chamber being provided with an outlet, which method comprises: displacing the chamber relative to the cable, passing the cleaning and lubricating liquid at a relatively high pressure to the nozzles in order to direct jets of relatively high pressure liquid onto the surface of the cable, operating a vacuum pump in communication with a vapor space of a tank for collecting used cleaning liquid and with the outlet of the chamber so as to cause a reduction of pressure in the vapor space and in the chamber to a value which is so much below atmospheric pressure that a flow of air from the surroundings along the sealing means and into the chamber is maintained, whereby any leakage of fluid from the chamber is prevented.
Claim 3
Dependent Claim
167 words
A cable cleaning and lubricating system comprising a chamber adapted to surround a section of a cable to be cleaned and lubricated and to be displaced relative to the cable, nozzles within the chamber for directing jets of relatively high pressure cleaning and lubricating liquid onto the surface of the cable, sealing means at both ends of the chamber and adapted to contact the cable, the chamber being provided with an outlet, and a conduit connecting the outlet to the vapor space of a tank for collecting the used cleaning and lubricating liquid, wherein a vacuum pump is in communication with the vapor space of the tank for reducing the pressure in the vapor space of the tank and in the chamber to a value which is so much below atmospheric pressure that, during normal operation, a flow of air from the surroundings along the sealing means and into the chamber is maintained, so that any leakage of cleaning and lubricating liquid from the chamber is prevented.
