An agricultural product application implement includes a system and method for indicating an amount of fluid stored. A pressure transducer installed at the sump of a fluid tank electronically measures and displays a fluid depth. Instrumentation, such as an instrument cluster unit for the implement, is programmed via software to convert the voltage output of the pressure transducer to a volume measurement displayed in the operator's line of sight. Software within the instrument cluster unit for self-calibrating accounts for varying densities of different chemical solutions. The pressure transducer is used in conjunction with a transfer medium to prevent corrosive chemical solutions from contacting the pressure transducer.

An easy grease filling machine is disclosed. The grease tilling machine comprises a drum cover, a pump body that goes through the drum cover, a grease pressing disc fitted on the pump body. The periphery of the drum cover is configured with a quick locking mechanism compatible to the rim of the grease packing drum and fixed with the drum body, and is matched by a grease pressing disc with its size automatically changeable when it moves up or down inside the drum body based on the different diameters of the drum body from bottom to top. The grease pressing disc comprises a disc body and a grease scraping skirt configured on the outer periphery of the disc body with its cross section shaped like an inverted V.

A gravity oiler assembly for for passively managing a fluid within an input fluid reservoir for use in an equipment fluid reservoir. The gravity oiler assembly comprises a fitting, the input fluid reservoir, and a nozzle. The fitting comprises an outer surface, an inner cavity, a top aperture, and a side apterture. The input fluid reservoir comprises a bottle being arranged with a fluid passage attached to the nozzle. The nozzle is arranged below the input fluid reservoir and inserted into the top aperture of the fitting. The gravity oiler assembly is configured to allow the fluid in the input fluid reservoir to enter a portion of the nozzle, the inner cavity and the side apterture. The gravity oiler assembly is configured to store the fluid in the input fluid reservoir and passively dispense the fluid into an equipment fluid cavity of the equipment fluid reservoir.

A manual lubrication system for a manual toilet flush pump on a manual toilet of the type used in boats and RV's. The lubrication system comprises a lubricant reservoir affixed in parallel to the housing of the manual toilet flush pump laterally opposite the toilet, with a movable lubricant pump head located below the operating handle of the manual toilet flush pump and having an operating axis generally parallel to the that of the manual toilet flush pump's operating handle. A positive manual shutoff normally keeps the lubricant reservoir isolated from the normal in-flow of water to and through the manual toilet flush pump except when lubricant is being manually added during a maintenance procedure.

Systems and methods are provided for remotely monitoring liquid lubricant levels for pump equipment. A system includes a reservoir to store lubricant and a lubrication gland to expose a shaft seal of the pump equipment to the lubricant. A feed line and a return line circulate the lubricant between the reservoir and the lubrication gland. A level sensor is configured to measure a fluid level in the reservoir. The level sensor uses a communication interface to transmit fluid level data a monitoring device mounted to the pump equipment. The monitoring device is configured to compare the fluid level data against stored alert thresholds and send, to a provider network, an alert signal when the fluid level data is below an alert threshold. If the fluid level data is not below an alert threshold, the monitoring device stores the fluid level data for periodic reporting.

A chainsaw (100) includes a power unit, a bar (120), a chain (122) operably coupled to the bar (120) to rotate around the bar (120) responsive to drive power from the power unit, an oil pump operably coupled to the power unit to deliver oil to the chain (122), and an oil 420 reservoir (400) configured to hold oil for delivery to the chain (122) via the oil pump. The oil reservoir (400) may include a main chamber (410) to receive the oil and an air chamber (420). The air chamber (420) may be formed adjacent to and distinct from the main chamber (410). The air chamber (420) is configured to define a space for an air pocket.

A lubricating can has a grease cup, bolt, piston, pressing base, bearing placement portion and a rotation driving component. The fixed end of the bolt is fixed on the grease cup bottom. The piston is housed inside the lubricating trough. The piston has a pressing surface, a bearing surface and a lateral ring surface that is tightly fitted on and can slide along the inner wall. The center of the piston is formed with a through hole and a plurality of lubricating guide holes. The through hole is sheathed on the bolt. The lower end pressing portion of the pressing base has a screw hole to fit the bolt. The bearing placement portion is defined and formed by the space between the lower end pressing portion and the bearing surface of the piston. The rotation driving component is configured on the upper end bearing portion of the pressing base.

By mounting a line blind valve (2) between a grease container (i) and a grease lubrication pump (3) replacement and mounting of the grease container can take place without leak of grease during the mounting as the outlet section must turn downwards during the mounting. By providing the installation with a line blind valve this can block grease leakage during the mounting and thereafter be opened. The valve (2) includes a flat central part (1o) with an opening (ii) which part can be displaced in relation to an upper positioned inlet section (4) and a lower positioned outlet section (8) and by displacement of the slide open and close for passage. In order to keep these parts (4, 8, 10) together a magnet (6, 7) is embedded in each of the two parts (4, 8) by which a sealed connection is secured with no air infiltration.
