摘要： A high-pressure fuel pump for an internal combustion engine. The high-pressure fuel pump includes an improved configuration that beneficially simplifies certain features of the high-pressure fuel pump. The fuel pump possesses an inlet check valve positioned along an inlet fuel circuit and an outlet fuel circuit of the high-pressure pump that provides a path for a low-pressure inlet fuel flow to and a path for a high-pressure output fuel flow from a pumping chamber of the fuel pump. Because of the configuration of the inlet check valve and the outlet check valve, the complexity of high-pressure fuel pump is beneficially reduced, decreasing the cost of components and assembly and improving the life and reliability of high-pressure fuel pump.

摘要： A device 10 for providing air to a tyre which is mounted on a rim (16) which itself is free to rotate about a fixed, that is, non-rotatable axle (22). A pump is provided which in use rotates with the tyre and which is configured to provide, when activated, air under pressure to the tyre. The pump drive system for activating the pump upon a loss of air pressure in the tyre consists of a first part that is rotationally connected to the tyre and a second part which includes a first clutch plate (42) which rotates with the first part whilst the pump is not activated. The pump is activated by inhibiting the second part of the drive system from rotating with the first part. Relative rotation between the first and second parts drives the pump to provide air under pressure to the tyre. There is a second clutch plate (26) which is configured so that it can be attached to the fixed axle (22) so that it itself is fixed, that is, non-rotatable. The first and second clutch plates (26, 42) are normally spaced apart. A clutch piston, moved by pressure in the tyre, engages the clutch by urging the first clutch plate (42) against the second clutch plate (26) upon the pressure in the tyre dropping below a predetermined value.

摘要： A system for delivering cryogenic fuels to an engine uses a plurality of cryogenic pumps operating in offset phases to deliver high pressure fuel with a minimum of pressure ripple. The cryogenic pumps use engine oil and a hydraulic pump for actuation via electrohydraulic valves. A charge pump maintains pressure in the feed line so that the cryogenic pumps can be located away from the cryogenic fuel tank. A control strategy for the hydraulic pumps allows output pressure and flow rate to be closely controlled and regulated.

摘要： A method for preventing a pressure in a crank chamber from excessively increasing without leading to an increase in weight or cost or causing damage to a pressurizing booster compressor. A compression chamber is formed by a cylinder, a cylinder head, and a piston reciprocal inside the cylinder. Rotation of an output shaft of an electric motor causes the piston to reciprocate via a crank shaft. A sealed crank chamber is defined inside a crank case. A pressurized gas supply tube supplies pressurized gas to be compressed into each of the compression chamber and the crank chamber. The crank case is formed from a hollow cylindrical body and an end plate facing the outside. A low-strength wall (a partition wall having a lower strength than another partition wall), which is configure to be broken under an allowable maximum pressure of the crank chamber, is formed on the end plate.
