A pneumatic liquid dispenser includes a container and a lid. When the lid is mounted on the container, the container supports passaging defining a gas supply inlet for receiving pressurized gas, a gas outlet for delivering pressurized gas to the container, and a gas flow path between the inlet and the outlet. A pressure valve is located between the gas supply inlet and the gas outlet. The pressure valve is configured to automatically permit gas flow along the gas flow path when pressure in the interior of the container is less than a threshold pressure and to automatically block gas flow along the gas flow path when pressure in the interior of the container is greater than the threshold pressure. When gas flows freely through the gas flow path, the gas pressurizes the container to dispense liquid in the container through a liquid passage.

A kit for changing the engine oil in a vehicle. The kit may include a bucket for collecting the spent oil. The kit may also include a dolly for rolling the bucket underneath the vehicle, and a collapsible stand for elevating the bucket to transfer the dirty oil to a recycling container. A spigot at the bottom of the bucket allows for draining the dirty oil into the recycling container. The bottom of the bucket is inclined toward the spigot, and the inner edge of the bottom is beveled to ensure complete emptying of the oil. The kit may include a hook for hanging the used oil filter to drain in the bucket. A magnet on the lid may be included to mount a wrench or other tools for easy access during the oil change procedure. A handle on the bucket and a leak-proof lid may complete the kit.

A retainer is rotationally driven about a axis of a ball bearing, and convex areas having pockets provided therein along a ball pitch circle of the retainer and concave areas between adjacent pockets is detected by a sensor. Grease is discharged according to phases of the convex areas and concave areas in the rotationally driven retainer from a dispenser having grease discharge ports arranged to face an annular space.

An apparatus configured to control fluid distribution between at least one fluid circulation system (2) associated with equipment (3) and at least two replaceable fluid containers (4), the apparatus having: a fluid path (5) configured to couple to at least one fluid port (6) of the fluid circulation system (2), and to at least one fluid port (7) of each of the replaceable fluid containers (4), the fluid path (5) having at least one valve (8) between the fluid circulation system (2) and at least one replaceable fluid container (4); and a control apparatus (9) configured to control the at least one valve (8) to control the flow of fluid between the fluid circulation system (2) and the at least two replaceable fluid containers (4).

An apparatus comprising: an identity determiner configured to determine an identity of a removable fluid container; a characteristic determiner configured to obtain a first characteristic based on testing the fluid of the fluid container; a data obtainer configured to obtain a second characteristic based on the identity; and a processor configured to control a fluid provider to provide fluid from the removable fluid container based on the comparison of the first characteristic and the second characteristic.

A method of transferring fluid in a motor system includes containing a first volume of fluid in a reservoir of a fluid container that is in fluid communication with a fluid receptacle of a motor and containing a second volume of fluid in the fluid receptacle. A first quantity of fluid is transferred from the fluid receptacle to the reservoir of the replaceable fluid container so as to mix the first quantity of fluid from the fluid receptacle with the volume of fluid in the reservoir of the replaceable fluid container A second quantity of fluid is transferred from the reservoir back to the fluid receptacle.

An emission-capturing apparatus includes a tank having an inlet and an outlet. The apparatus further includes a muffler fluidly coupled with the outlet to intercept fluid exiting the outlet, permit passage of gas through the muffler, and inhibit passage of liquid through the muffler. The apparatus further includes a hose having a tank end and a distal end. The tank end is coupled to the inlet. The apparatus further includes a fitting fluidly coupled to the distal end of the hose. The fitting is configured to be fluidly coupled to an end section of an ejection port of a vehicle to receive an emission from the ejection port.
