A fuel storage assembly includes a power source, a first tank, a fuel pump, an electric relay, a second tank, and a shut-off device. The fuel pump is adapted to remove fuel from the first tank. The electric relay is electrically connected between the power source and the fuel pump for terminating electric power to the fuel pump. The second tank is adapted to receive the fuel removed from the first tank. The shut-off device is located in the second tank and is electrically connected to the electric relay, and is configured to detect a shut-off level of fuel in the second tank. Upon detection of the shut-off level, the shut-off device effects shut-down of the fuel pump via the electric relay.

A fluid pressure control device includes a first circuit system having a first pump and a first control valve. The first circuit system includes an intermediate cut valve provided downstream of the first control valve in a first intermediate passage and which connects and disconnects a connection between the first intermediate passage and the tank, and an external output port communicating at a part downstream of the first control valve in the first intermediate passage and upstream of the intermediate cut valve, the external output port being capable of externally supplying working fluid discharged from the first pump.

A system for controlling the mixing ratio of a multi-component mixture including a first pump connectable to a source of a first component and a second pump connectable to a source of a second component. The first and second pump being associated with at least one linear sensor for generating an output indicative of actual pump speed or shaft displacement of the pump. The system further includes a control circuit operative to utilize the output of the linear sensor of one of the pumps to generate a control signal for controlling the output of the other pump.

The invention is directed to a divider block assembly made from one piece of material. Traditional divider blocks require modular sections so that piston alignment can be calibrated precisely. The current invention uses replaceable pistons and sleeves that are suitable for use at high fluid pressures. The use of these pistons also allows for a single, bodied, one-piece, metal divider body, rather than the conventional multiple block divider blocks, which allows for a more efficient manufacturing method and stronger, more reliable, and more efficient lubricant dispensing system. The use of any of these aspects separately can improve performance, and not all are required in every embodiment.

Examples of a jet control device are described. The jet control device can comprise a jet deflecting member that is configured to intercept and/or collide with a high speed jet emerging from a jet formation location. The interaction of the jet deflecting member and the jet can cause the high speed jet to be dispersed into a plurality of jets with a number of flow directions which may be sideways to an initial direction of the high speed jet. In one embodiment the deflecting member can include a liquid guide formed by injecting a fluid out of an outlet nozzle so that the liquid guide extends longitudinally away from the outlet nozzle. In another embodiment the deflecting member can include an array of solid pellets injected through an outlet in a direction of the emerging high speed jet and configured to collide with the emerging jet thereby deflecting its initial direction.

A hydraulic control system for vehicles is provided. A switching valve (34) that is adapted to provide a communication between an electric oil pump (25) and a drain passage while inhibiting a delivery of the oil from the electric oil pump (25) to the control object (20, C) when an output pressure of the mechanical oil pump (9) is higher than a predetermined level, and to provide a communication between the electric oil pump (25) and the control object (20, C) through a predetermined oil passage when an output pressure of the mechanical oil pump (9) is lower than the predetermined level. The electric oil pump (25) discharges oil before establishing the communication between the electric oil pump (25) and the control object (20, C) as a result of reduction in the output pressure of the mechanical oil pump (9) to be lower than the predetermined level.
