Abstract: In a valve member, supply and discharge apertures of fluid are formed at a body having a fluid space E. A one electrode Da including a contact T is provided at an aperture edge of the supply aperture and/or a peripheral part of an aperture edge of the body. The body includes another electrode Db, and stores a valve member made of a conductor and opening and closing the supply aperture, and a coil spring made of a conductor and urges the valve member. A guide member made of a conductor is attached onto the valve member. The guide member is formed to secure a flow path of the fluid from the supply aperture to the discharge aperture while being slidable in the fluid space E, has a reception surface facing one end face of the fluid space E while receiving the fluid from the supply aperture.

Abstract: The invention provides a lubricating grease composition with a worked penetration of 400 to 500 for a machine tool equipped with an automatic lubricator, containing a base oil having a kinematic viscosity at 40° C. of 10 to 200 mm2/s and 0.1 to 10 mass % of solid particles insoluble in the base oil. The lubricating grease composition of the invention can be fed using the automatic lubricator attached to the machine tool, and can prevent the stick-slip from occurring on the sliding lubrication portion of the machine tool.

Abstract: A lubricating method and apparatus for a circular knitting machine which involves inputting operating conditions for the circular knitting machine from an operating conditions input device 30, after which a pump squirt quantity per squirt is computed by a squirt quantity computing device 33 and set in a squirt quantity setting device 21, a pump squirt velocity is computed by a squirt velocity computing device 34 and set in a squirt velocity setting device 22, and an intermittent pump operating period is computed by an intermittent period computing device 35 and set in an intermittent period setting device 24. Subsequently, a start signal is sent from a start signal sending device 25 after each set intermittent period, and a pump drive device 23 drives the pump 12. As a result, an appropriate quantity of lubricating oil is squirted from a nozzle 13 towards a cam groove 4 of a cam 5 for a duration of at least one revolution of a row of needles 1 of the circular knitting machine.

Abstract: A lubricating device for a knitting machine capable of feeding lubricating oil in proper quantities while eliminating the necessity of forming the oil into mist, to thereby accomplish a lubricating action with high efficiency without deteriorating the environment. The lubricating device includes oil/air mixing sections which are defined in a lubricating distributor so as to communicate with oil passages and air passages. The mixing sections each are adapted to mix lubricating oil fed thereto through the oil passage by means of an oil feed valve and compressed air fed thereto through the air passage by means of an air feed valve, resulting in the lubricating oil being fed to a lubricated section of the knitting machine while being carried on the compressed air.

Abstract: A lubricating fluid comprising a refined petroleum base stock containing minor controlled amounts of each of a finely-divided, particulate molybdenum disulfide, a viscosity index improver, an anti-wear agent and a corrosion inhibitor.
