A lubrication system includes a progressive distributor that is configured to dispense lubricant to a consumer. The lubrication system also includes a control device and at least one sensor that is configured to determine at least one lubricant pressure inside the lubrication system. The control device is configured to receive measured values from the at least one sensor and to recognize a lubrication cycle based on the measured values and also to determine an average pressure of the lubrication cycle, to perform a comparison of the average pressure and at least one normal pressure of the lubrication system, and to determine a state of the lubrication system based on a result of the comparison.

A method for monitoring a fluid system for lubricating a mechanical system. The fluid system comprises a spraying circuit connected to a main fluid circuit and to a back-up fluid circuit. The back-up fluid circuit comprises a back-up check valve closed in a nominal operating mode. The method comprises a monitoring phase comprising the generation of a first alert in the presence of the detection of a malfunction making the main fluid circuit inoperative and the back-up check valve in an open state and the generation of a second alert different from the first alert in the presence a malfunction and the back-up check valve in a closed state.

A lubricant deterioration detection device of the present invention includes a gas sensor that selectively detects a carbonyl compound.

Systems and methods are provided for enabling communication, without breaching the engine firewall, between a datalogger located on one side of the firewall and one or more sensor devices that are located on the opposite side of the firewall. The systems and methods described herein can allow a transmitting node (i.e., a transmitting datalogger) to transmit collected data (from an auxiliary sensor) to a receiving node (i.e., a receiving datalogger) while reducing or minimizing various difficulties associated with addition of an auxiliary sensor in the engine environment. The transmission of data from the transmitting node to the receiving node can correspond to wired data communication or wireless data communication.

A fitting for a lubrication point of a device to be lubricated and a connector for removably connecting to such fitting to provide a lubricant from a lubrication device via the fitting to the device to be lubricated are disclosed. The fitting comprises an integrated circuit for providing an identification code to identify the fitting, and a first electrical contact for establishing an electrical path between the integrated circuit and a processor of the connector when a connection between the fitting and the connector is established. The connector comprises the processor and a second electrical contact for establishing the electrical path. The integrated circuit is adapted for transmitting data, including the identification code, via the first electrical contact to the processor.

A lubrication system for supplying a lubricant to at least one lubrication point includes at least one lubricant line and at least one lubricant system component that is connected to the lubricant line. The lubrication system component includes at least one movable element and/or the lubricant line includes at least one movable portion. The system also includes at least one energy-generating element, such as a piezo element or a magnet and coil, configured to interact with the at least one movable element and generate energy from a movement of the at least one moveable element.

A lubrication system configured to supply a lubricant to at least one lubrication point includes a lubricant pump configured to pump the lubricant to the at least one lubrication point, a lubricant distributor configured to distribute the lubricant at the at least one lubrication point, a controller configured to control at least the lubricant pump and/or the lubricant distributor, a lubrication system monitor configured to monitor a monitoring variable of the lubrication system, and a signal transmission device configured to wirelessly transmit a signal indicative of the monitoring variable provided by the lubrication system monitor to the control device and/or to a device functionally associated with the lubrication system and/or to receive data from the control device or from the device functionally associated with the lubrication system.

A method for determining a degree of loading on a filter medium of a filter device on a vehicle through which a fluid flows includes determining an operating characteristic of the filter device based on at least one operating quantity of the vehicle and comparing a predefined reference characteristic of the filter device with the operating characteristic. The degree of loading is derived from a result of the comparing step.

A pump with a reservoir of a lubricant, including a hollow body in which a piston, loaded by a pressing element, sealingly slides, at least a port for loading the lubricant in a compartment defined by the inner wall of the hollow body and by the piston, and at least a valve for exhausting air trapped in the compartment together with the lubricant during a loading step.

A lubricating system for supplying at least one lubricating point with lubricant is described. The lubricating system is equipped with at least one feed device and at least one line extending between this feed device and a lubricating point. In order to very easily and effectively monitor and indicate the severance of a lubricant line, an electrical connection is respectively provided on the feed device and the lubricating point. An electric conductor extending between the two connections is assigned to the line. A monitoring device is assigned to the line in such a way that it generates a signal when the electric conductor is interrupted. The invention furthermore pertains to a vehicle, particularly a construction machine, which is equipped with such a lubricating system.
