A fluid storage and dispensing system that safely and efficiently stores all grades of motor oil is provided. The system is configured to accurately dispense motor oil into vehicles. The system may also be used for the storage of and dispensing of other fluids.

Connection devices for connecting together a filter, a regulator, and a lubricator, which constitute a fluidic unit, are each provided with: a base member having a hole; a pair of first and second fastening members which are mounted to one side surface and the other side surface of the base members; and first and second holders held by the first and second fastening members. The first and second holders are engaged with the engagement protrusions of the filter, the regulator, and the lubricator, and first and second nuts are engaged with the first and second fastening members through threads to connect the fluidic devices together through the first and second holders. Caps are fitted over the first holders and the first nuts.

The wide-angle constant velocity joint (100) includes: a central core (101) forming respective inner yokes (24, 25) for connection and in which there is housed a guide disc (11); and outer yokes (103, 105). The central core (101) forms a lubricant reservoir (1) in communication with an annular seat (7) in which the guide disc (11) is slidingly received.

A fluid system of a machine. The fluid system includes a fluid reservoir, a pump coupled to the fluid reservoir, a filter coupled to the pump and a valve assembly. The valve assembly includes a first port, a second port coupled to the first port and to the fluid reservoir, a third port coupled to the first port, and a first check valve positioned between the first port and the second port. The fluid system further includes a second check valve positioned between the filter and the third port.

A transmission device includes a casing accommodating a transmission gear and having an oil sump for retaining oil. The oil in the oil sump flows from a lubrication pump through a lubrication passage and is injected to the transmission gear. A connection portion is provided in a part of the lubrication passage, which part is disposed outside the casing. A direction control valve is provided downstream of the lubrication pump and upstream of the connection portion in the lubrication passage with respect to a flow direction of the oil. The direction control valve is configured to open the lubrication passage when a hydraulic pressure in the lubrication passage exceeds a predetermined value and to close the lubrication passage when the hydraulic pressure is equal to or lower than the predetermined value.

A drive device includes a gear unit, which is able to be driven by a motor and includes a pressure-lubrication system. The pressure-lubrication system has a distributor block, having a continuous longitudinal bore and continuous transverse bores. The distributor block is arranged as a single piece, in particular from metal such as steel or aluminum.

A lubricant or fluid distributor may have a housing made in one piece and comprising an inner wall and an outer wall. The inner wall encloses an inlet chamber fluidly connected with an outside of the housing through a fluid inlet. A main chamber may be formed in between the outer wall and the inner wall, the main chamber fluidly connected with the inlet chamber and fluidly connected with the outside of the housing through one or more fluid outlets. A lubricant fitting member may be encapsulated within the inlet chamber. A system with the lubricant or fluid distributor may have a part to be lubricated.

A progressive distributor for lubricant includes a housing block having an inlet and a plurality of outlets and a plurality of metering pistons received in associated piston bores in the housing block. Each piston bore is associated with two lubricant outlet bores, and each metering piston is displaceable and configured to alternatingly release the one or the other lubricant outlet bore in order to dispense the metered lubricant amount to the lubricant outlet bore. The piston bores are fluidically connected to the lubricant inlet bore and to each other via connecting bores in order to transfer lubricant to the other piston bores. A dummy piston is disposed in one of the piston bores that permanently closes both the lubricant inlet bore and both lubricant outlet bores, and includes at least one bypass passageway that fluidically connects two of the connecting bores to each other.
