A lubricant dispensing system is provided. The dispensing system includes a lubricant supply, a lubricant dispensing nozzle and a control panel. The dispensing nozzle includes a nozzle body with a fluid passageway therein which is in fluid communication with the lubricant supply, an electrode assembly for electrostatically charging lubricant in the fluid passageway and at least one discharge orifice through which electrostatically charged lubricant can be discharged. The discharge orifice is defined by at least one spray needle having a first end in fluid communication with the fluid passageway and a second end that extends outward of the nozzle body. The control panel directs the flow of lubricant from the lubricant supply to the lubricant dispensing nozzle and controls the electric power supplied to the electrode assembly.

The invention relates to a spraying tool (20), in particular as part of a mould-spraying device for spraying at least one section of a wall of a mould with working medium, the spraying tool comprising a plurality of spraying elements (22) for dispensing working medium, and at least one working-medium supply line (36) which supplies working medium to the plurality of spraying elements (22). According to the invention, at least some of the spraying elements (22), the spraying nozzles (62) of which point downwards during operation, are equipped with a separate valve unit (42) which is adjacent to the spraying nozzle (62) and the valve element (56) of which is prestressed elastically into a closed position in which it prevents the dispensing of working medium, but can be transferred under the action of a hydraulic and/or pneumatic pressure into an open position in which it permits the dispensing of working medium.

A nozzle for a mist lubricator system has an emitter head located in a tubular housing. The emitter head has tapered passageways terminating at an end from which lubricant drops are directed to a target to be lubricated. The emitter head can be incorporated in lubricator systems of various types, including those utilizing a cycling feed metering system. A nozzle constructed in accordance with the present invention can be used in reduced airflow systems and exhibits substantially lessened lubricant loss during low and no airflow periods.

The invention relates to a device for producing a lubricant mist in a compressed air line, comprising an air duct (2) of a housing (1), a control valve (5), notably a proportional valve, which by way of a control gate (14) modifies the open flow area in accordance with the pressure differential between the inlet (3) and outlet (4) of the air duct (2), and a lubricant reservoir (7) which via a filler valve (6) having a valve body (15) is connected with the inlet (3) of the air duct (2) and via a suction line (riser pipe 8) and an oil mist lubricator (12) is joined to the outlet (4). The filler valve (6) closes at a pressure differential greater than approximately 1 bar and the control valve (5) and the filler valve (6) are positioned in physical proximity to each other. The control gate (14) of the control valve (5) and the valve body (15) of the filler valve (6) are configured as a single piece and made of an elastic material.

A size is applied to a moving strand (14). A collet (22) is rotated to wind the strand (14) and build a package (19). The strand (14) is reciprocated with a strand reciprocator (30) to lay the strand (14) in a pattern on the package surface (20) as the package (19) rotates. The strand reciprocator (30) is lubricated with a lubricant which is compatible with the size. An apparatus is also provided for winding the fiber strand (14) to build and form a cylindrical strand package (19) of wound strand having a radially outer surface (20) with first and second edges (a) and a central portion (20b) therebetween. A strand reciprocator (30) is mounted to guide the strand from edge to edge of the package and to lay the strand in a helical pattern on the package surface (20) as the package (19) rotates. A lubricator (70) for atomizing a lubricant creates a fog of small airborne lubrication particles. Lubrication locations include the cam (32) surface and the grooves (34) provided thereon, the cam (32) bearings and the roller bail bearings. A roller bail (42) is mounted for contacting the package surface (20) as the package (19) is being built for holding the strand (14) in place on the package (19). The roller bail (42) is divided into separate rollers (46) with each roller (46) contacting the package surface (20) at one of the edges (a) and not contacting the central portion (20b).

摘要:
A package of treatment and control elements, for example for filtering and discharging condensate (11), pressure regulation (12) and lubricant dispersal (13) for compressed air distribution systems comprises a plurality of modular units interlocked by connection means in the region of respective heads each traversed by a bore (15) for the passage of compressed air. Said connection means comprise raised portions (16) formed on lowered stubbed opposed faces of each of the said heads, each of which portions (16) is adapted to abut a matching portion of the head of the adjacent unit, the ends of said portions (16) being shaped with inclined surfaces (17) which are engaged by matching surfaces of seats formed in a pair of opposed blocks (18) mutually locked by through screws.

A coupling is provided for a pressure or vacuum fluid system having a bowl and filter head (10, 26) that connect together by relative rotation to engage bayonet coupling formations (32, 34, 94) thereof. When connected together the bowl (10) and filter head (26) have outer walls (16, 104) overlapping with an intervening seal (22) therebetween. A pressure relief valve (38) is provided in one of the members (10). A latch (36, 108) engages at an angular position of said members (10, 26) where the bayonet coupling is established to prevent relative rotation of said members (10, 26) and is prevented from engagement at other angular positions. The latch (36) is decoupled from the valve (38) when in its engaged state but is operatively coupled to the valve (38) when in a disengaged state to open said valve (38), fluid flow therethrough providing an audible warning when a pressure differential exists across the valve (38).
