A flow-through pressure regulator (10) includes a housing (20) having an inlet and an outlet offset along a longitudinal axis. The housing is separated by a divider (30) into a first chamber (40) and a second chamber (50). The divider has a passage (60) that communicates the first chamber with the second chamber. The passage includes a first section extending along the longitudinal axis and a second section extending transverse to the longitudinal axis. A closure member (70) permits or inhibits flow through the passage.

The fuel injector (10) comprises an air assist injector valve body (28) and an air assist back up washer (37), having two or more flow channels (76), contained within the valve body (28). The fuel injector (10) further comprises a shroud member (52) having a non-parallel surface and a flat surface, wherein the non-parallel surface abuts up against the back up washer (37) so the flat surface of the shroud member (52) combined with the flow channels in the back up washer (37) meter and/or direct the air flow.

A fuel injector for controlling fuel flow to an internal combustion engine and a method of setting dynamic calibration for the fuel injector. The fuel injector comprises a body, a seat, an armature assembly, a resilient member, and a member. The body extends along a longitudinal axis. The seat is secured to the body and defines an opening through which fuel flows. The armature assembly moves along the longitudinal axis with respect to the body between first and second positions. The first position is spaced from the seat such that fuel flow through the opening is permitted, and the second position contiguously engages the seat such that fuel flow is prevented. The resilient member biases the armature assembly toward the second position. And the member extends parallel to the longitudinal axis between a first portion and a second portion. The first portion supports the resilient member and engages the body, and the second portion has a filter. The method comprises providing the member extending between the first portion and the second portion, fixing the filter to the second portion, moving the member along the longitudinal axis with respect to the body; and engaging the first portion with respect to the body such that the first portion supports the resilient member in a predetermined dynamic state.

The invention relates to an electromechanical regulating device having an actuating element (2) and an actuating drive (1). Said actuating drive comprises at least a first electromagnet with a first coil (13) and a second electromagnet with a second coil (15), in addition to an armature that can move between the locating surfaces (17a, 17b) of the first and second electromagnets and at least one recoil means (18a, 18b) mechanically coupled to the armature. In order to start the regulating device, the second coil is powered until a first predetermined condition is fulfilled and the first coil is then powered once a second condition is fulfilled until the armature comes into contact with the locating surface (17a).

A fuel of air system component for a motor vehicle, constructed with shape memory alloys (58) to control fuel flow as a function of temperature or electrical means. The shape memory alloy (58) changes shape at a defined temperature, or in a particular temperature range, thereby affecting a control feature internal to a component in the fuel system, and as a result, changing the fuel flow and/or pressure characteristic. The component may be a biasing spring. The shape memory alloy is an intermetallic compound or alloy which exhibits a shape transformation when heated or cooled through its transformation temperature.

摘要:
A vehicle access system that includes an electronic key (31) ensures that the vehicle transmission is in a proper condition before power to the selected vehicle components is turned off. A control panel (23) within the vehicle allows a driver to activate a switch (34) indicating a desire to turn off the vehicle engine. A controller (30) first determines whether a valid authentication code is received from a passive signaling device (31). Once validation is complete, the controller turns off the engine. Next, the controller determines that the vehicle is in the appropriate gear. If the transmission must be switched to the appropriate gear, the controller provides an indication to the driver that the transmission must be switched before the power to the accessory components will be turned off.
摘要:
A vehicle access system utilizes an authentication code from a passive signaling device before access to the vehicle will be granted. Simple operation of a manually operated device supported on the exterior of the vehicle combined with the presence of the proper authentication code provides a vehicle owner with the desired access. Additional access functions are possible without requiring complicated actions by the vehicle owner. Additionally, security features ensure that the passive signaling device is outside of the vehicle near the entry point whenever a vehicle access command is generated.

A system for measuring the weight of a seat occupant is used to control airbag deployment. The system includes a plurality of weight sensors that have a first end mounted to a seat riser and a second end mounted to a seat frame or track member. The weight sensors have a central bendable portion that extends between the first and second ends. A groove is formed in one of the external surfaces of the central bendable portion to localise strain. A full bridge strain gage assembly is mounted on a surface of each of the weight sensors, opposite from the groove, for generating a weight signal in response to measuring deflection of the central bendable portion. A central processor determines seat occupant weight based on the weight signals and an airbag control module communicates with the processor. The control module controls deployment force of the airbag based on seat occupant weight.
