An engine assembly includes a small air-cooled engine and a dry sump lubrication system including an external oil reservoir, wherein the dry sump lubrication system has an overall oil capacity that provides at least five hundred hours of engine oil life.

An automatic lubricator for lubricating an object. The lubricator includes a housing with a coupling section configured to couple with a lubricant container containing a lubricant. The lubricant container includes a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. An electric motor is configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action. At least one sensor is arranged within the housing and configured to provide a sensor signal indicative of a distance between the at least one sensor and the piston of the lubricant container, and a control circuitry configured to determine, based on the sensor signal, at least one lubrication parameter indicative of the at least one lubrication action.

An accumulator includes a tank body having a communication port that communicates the lubricant accommodating space capable of accommodating lubricant with the outside, the tank body extending around an axis, a piston that moves in the axial direction in the tank body to vary the size of the lubricant accommodating space, a spiral spring mechanism having a spiral spring, and a rotational force transmission member that converts a linear movement of the piston into a rotational force around the axis to transmit the converted rotational force. The rotational force transmission member converts a rotational movement due to a restoring force of the spiral spring into a force in the axial direction to move the piston in the axial direction.

The invention relates to a lubricant dispenser comprising a storage container (1) filled with lubricant and a pump unit (2) which can be connected to or is releasably connected to the storage container and by means of which the lubricant can be pumped from the storage container (1) to an outlet (5) of the pump unit (2) and is equipped with an electronic controller (35). The lubricant dispenser is characterized in that the storage container (1) is equipped with an electronic coding means (36) which can be connected to the electronic controller (35) of the pump unit (2) and can be read by same so as to transmit information in the assembled state in order to identify the storage container (1).

A lubricant pump includes a housing mountable to the upper end of a lubricant container and having a vertical central bore, an outlet passage extending between the central bore and an outlet port fluidly connectable with the lubricant distributor and a vent chamber having an inlet and an outlet. A vent inlet passage extends between the central bore and the vent chamber inlet and a vent outlet passage extends between the vent chamber outlet and a vent outlet port fluidly connectable with a container cavity. A movable valve element is disposed within the vent chamber and displaceable along an axis between a position in which the valve element obstructs the chamber inlet and/or the chamber outlet and a second position in which the chamber inlet is fluidly connected with the chamber outlet to provide an internal flow path from the central bore to the vent outlet port.
