A protector protects a high-pressure fuel pump of an internal combustion engine. The protector and the high-pressure fuel pump are fastened to an engine body by a bolt inserted through a metal collar. The protector further includes an elastic insulating layer located between the collar and a carbon fiber reinforced plastic portion. The collar is embedded in the carbon fiber reinforced plastic portion with the insulating layer compressed.

A plastic injection rail, subjected to an inner relative pressure for an engine, includes: a conduit body; a plug; and a junction part overmolded within a contact area defined by portions of the plug and the end of the conduit body. The junction part can fixedly attach the plug into the end of the body, and includes a first portion arranged around the contact area, and a second portion within a space between the conduit body and plug. The plug has a hollow projection that extends toward the plug head. The plug body includes hollow rings including a primary ring arranged at the level of the free end of the plug body and secondary rings arranged between the primary ring and plug head. The junction part presents a generally cylindrical shape formed by rings including a primary ring closest to the contact area, and secondary rings.

The valve according to the present invention, in particular, a fuel injector, is characterized by having an improved sealing at its spray-side end. The fuel injector (1) includes an excitable actuator (15) for actuating a valve closing body (12), which together with a valve seat surface (14) formed on a valve seat body (13) forms a seal seat, and spray openings (4) formed downstream of the valve seat surface (14), and a valve seat support (10), which accommodates the valve seat body (13), forms a portion of a valve housing (22) and is fixedly connected to the valve seat body (13). A plastically deformable sealing element (45) is introduced into an annular gap (35) between the valve seat support (10) and the valve seat body (13) to avoid corrosion and damage of a weld seam (30). The fuel injector is particularly suitable for directly injecting fuel into a combustion chamber of a mixture-compressing spark ignition internal combustion engine.

In a valve apparatus, a housing includes a plurality of through holes through which a fluid flows. A first valve member opens and closes a first through hole. A second valve member opens and closes at least one second through hole. A fixed core does not move relative to the housing. A coil forms magnetic field. A first movable core moves integrally with the first valve member. When the coil forms the magnetic field, a magnetic attractive force is generated between the first movable core and the fixed core. A second movable core moves integrally with the second valve member. When the coil forms the magnetic field, a magnetic attractive force is generated between the second movable core and the fixed core. A magnetic constriction portion is provided between the fixed core and the first movable core. The second through hole is opened after the first through hole is opened.

A motor vehicle fuel pump cover is provided for covering a fuel guide region of a motor vehicle fuel pump by way of a cover housing. A phase change core is received in the cover housing. The phase change core is designed to change the phase state thereof while receiving thermal energy from the fuel guide region. The phase change core is designed for phase change at a temperature of more than 60 C.

A fuel pressure regulator includes a fuel inlet; a fuel outlet; a seating surface; and a valve member assembly. The valve member assembly includes a poppet and also includes a sealing member which is made of an elastomer material and which is annular in shape and including a sealing member surface. The sealing member is supported by the poppet. The valve member assembly is moveable between 1) a closed position in which the sealing member surface engages the seating surface, thereby preventing fuel flow from the fuel inlet to the fuel outlet and 2) an open position in which the sealing member surface is spaced apart from the seating surface, thereby allowing fuel flow from the fuel inlet to the fuel outlet.

A fluid injector includes a valve assembly constructed and arranged to control flow of fluid from an inlet to an outlet of the injector. A metal housing surrounds at least a portion of the valve assembly. A plastic body is molded over at least a portion of the housing. A distal end of the body defines an integral stepped portion extending from the body. A carrier surrounds at least the distal end of the body. A seal member is in contact with at least the stepped portion and a surface of the carrier to prevent liquid from entering a space between the housing and the body.

A stator coil assembly is provided comprising: a stator having a stator core; a cover positioned within the stator core; a top section coupled to the cover to define an interior region, the top section including a pair of protrusions, each protrusion having a bore extending therethrough; a bobbin disposed within the interior region; a plurality of coil windings wrapped around the bobbin; a pair of lead wires, each lead wire extending through a corresponding protrusion bore and connecting to the coil windings within the interior region; and a pair of hermetic seals, each hermetic seal surrounding a corresponding lead wire within a protrusion bore to hermetically seal the interior region.

A fuel injector includes a nozzle body configured to be inserted into a fuel injector receiving bore of the internal combustion engine along a nozzle body axis; a valve housing held in fixed relationship to the nozzle body; and a first locating pin and a second locating pin each extending from the valve housing. The first locating pin extends from a first locating pin fixed end which is fixed to the valve housing to a first locating pin free end. The second locating pin extends from a second locating pin fixed end which is fixed to the valve housing to a second locating pin free end. The first locating pin and the second locating pin elastically deform when inserted into the bore, thereby preventing rotational movement of the fuel injector about the nozzle body axis.

A fuel injector isolator includes a support member which is rigid and which is annular in shape being centered about an axis such that the support member has a support member inner periphery which circumferentially surrounds the axis and includes a concave region. The fuel injector isolator also includes an isolation member which is resilient and compliant and which is annular in shape being centered about the axis such that the support member has an isolation member outer periphery and an isolation member inner periphery which accommodates the fuel injector therein. The isolation member is located within the support member inner periphery and includes 1) an isolation member outer periphery upper retention surface which engages the support member first end surface and 2) an isolation member outer periphery lower retention surface which extends into the concave region and engages the concave region of the support member.
