Abstract

A lubricant pump system includes a pump assembly which has a housing with an interior pumping chamber having an inlet. At least one pumping unit is disposed at least partially within the pumping chamber and is configured to displace lubricant from the pumping chamber through an outlet. The housing has a pump interface with an opening fluidly coupleable with the pumping chamber inlet and a pump valve controlling lubricant flow through the pump interface opening. A reservoir includes a body connectable with the pump housing and having a central axis, an interior storage chamber for containing a quantity of lubricant and a reservoir interface engageable with the pump interface. The reservoir interface includes an opening fluidly coupleable with the storage chamber and fluidly coupleable with the pump interface opening. The reservoir body includes a reservoir valve controlling lubricant flow through the reservoir interface opening.

Abstract

A drive mechanism including a pneumatic cylinder housing, a piston reciprocating in the housing between a first and second dead centers, a pumping shaft driven by the piston, a valve unit, a gas inlet, a gas outlet, the gas inlet is in fluid communication with a first chamber of the cylinder volume, and a second chamber of the cylinder volume in fluid communication with the gas outlet, when the valve unit is in a first state. The gas inlet is in fluid communication with the second chamber of the cylinder volume, and the first chamber of the cylinder volume in fluid communication with the gas outlet, when the valve unit is in a second state. The drive mechanism provides a valve unit actuator having a magnet located adjacent the valve unit and configured to alternately shift the state of the valve unit between the first state and the second state.

• F04B 9/125 - Piston machines or pumps characterised by the driving or driven means to or from their working members the means being fluid the fluid being elastic, e.g. steam or air having only one pumping chamber reciprocating movement of the pumping member being obtained by a double-acting elastic-fluid motor

Abstract

A lubrication system comprising a motor, a positive displacement pump driven by the motor, a lubricant container in fluid communication with the positive displacement pump and at least one lubricant outlet in fluid communication with the lubricant container. The positive displacement pump is arranged to carry out at least one discharge stroke to dispense lubricant from the at least one lubricant outlet when the lubrication system is in use. The lubrication system also comprises a control unit that is arranged to determine an amount of lubricant that is dispensed from the lubricant container via the at least one lubricant outlet when the lubrication system is in use. The control unit is arranged to monitor current supplied to the motor to obtain a motor current signal, and to determine a number of the discharge strokes from the motor current signal.

Abstract

The invention relates to an oval gear meter for flow measurement, the meter comprising: two oval-shaped gears (1, 2) arranged to rotate in synchronism in a chamber provided in a housing (3), through which chamber a medium to be measured is arranged to flow, the rotating motion of the gears (1, 2) being pro-portional to the flow rate. The meter is equipped with means for detecting the rotating motion of the oval gears (1, 2). The means for detecting the rotating motion of the oval gears (1, 2) comprise a permanent magnet (8) arranged to one of the oval gears (1 or 2), centrically with the rotating shaft (7) thereof, and a sensor circuit (9) arranged on the outer surface of the housing (3) wall, at a location coinciding with that of the permanent magnet (8).

Abstract

The invention relates to an arrangement in connection with a central lubrication system. The arrangement includes a lubricant vessel, a pump unit, a control unit, pipe systems, a pressure monitor unit, at least one lubricant feeder provided with at least one piston which moves due to the influence of the pressure of a lubricant present in the pipe system/object to be lubricated, and a movement monitor unit to monitor the operation of the feeder. The movement monitor unit includes a sensor part mounted to a nipple manufactured from a weakly magnetable material. The nipple includes a permanent magnet to generate a magnetic field, and a sensor for detecting movement of the piston, and an electronics part which processes a signal received from the sensor and forwards this processed signal to the control unit.
