Abstract: A lubricant metering device includes a cup-shaped body with a supply passage coupled to a valve element, a hollow tubular body with a free end facing the valve element, a piston slidingly sealed inside the cup-shaped body and along an external surface of the tubular body, an elastic element exerting a load on the piston towards the supply passage, delineating an accumulation chamber facing the valve element and a dispensing chamber in constant communication with the cavity of the tubular body, also in communication with a delivery passage, the valve element closing the free end of the tubular body, isolating the cavity from the accumulation chamber and allowing communication with the supply passage, or isolating the accumulation chamber from the supply passage and allowing communication with the cavity. A stop limits the piston stroke towards the elastic element to adjust the dispensing of lubricant.

Abstract: A system for distributing semisolid lubricant, including a semisolid lubricant tank and a high pressure pumping system that intermittently feeds, during a lubrication cycle, at least one first duct, the at least one first duct feeding a plurality of distributors adapted to sort the semisolid lubricant to a plurality of users; a controlled suction/delivery device, fluidly associated with the first duct, for controlled suction/delivery of a part of the semisolid lubricant conveyed by the first duct. The controlled suction/delivery device configured to suck a volume of semisolid lubricant from the first duct during a step of inactivity of the pumping system on the first duct, and to introduce the previously suctioned semisolid lubricant in the first duct during a step of activity of the pumping system on the first duct.

Abstract: An over-pressure indicator, including a cup-shaped body having, on its bottom, a hole inside which is sealably housed a mobile element loaded by a spring towards the bottom of the cup-shaped body, the mobile element facing an indicator sensitive part for communication with an area where pressure verification is wanted. The mobile element coupled with a signaller of a movement thereof. The spring pressed by a pre-loading ring nut screwed onto the cup-shaped body. The nut torsionally removably coupled with a calibration cap of the indicator. The calibration cap having at least one stop that, when it abuts against a portion of the cup-shaped body, limits further screwing of the nut thus determining pressure beyond which mobile element movement is allowed. The movement causing intervention of the indicator so by coupling the suitable calibration cap and indicator and screwing it in fully, setting the indicator intervention pressure is possible.
