A fuel cut valve (20) is disposed at a higher position than a fill up level (3) in a fuel tank (1) and communicates with an evaporative passage (16) communicating between the fuel tank (1) and a canister (15) through an orifice (22). Further, a volume cham...

The circuit includes a control unit for generating pulse-width modulated signals for driving an electromagnetic regenerative valve. A solenoid coil is supplied with the signals via a switch. A free-running diode is provided on the solenoid coil for suppres...

A combination solenoid operated flow control valve and solenoid operated by-pass valve and pressure transducer are disposed in a common housing with a common electrical receptacle for connection thereto. The pressure transducer senses differential pressure...

The valve includes a magnetic armature (5) having a seal (6) fastened to it, with the armature being held by two leaf springs (9,10) coupled to the valve casing (2).

The device has at least one coil, at least two electric connection contacts (2), an armature, an armature counter piece (4) and a short circuit plate (3). The armature counter piece is electrically connected to the short circuit plate and an electrically c...

Valve (1) for sealing the face of a sealing seat (4) lying in the lifting direction of a sealing element (2) comprises a magneto inductor (6) and a restoring spring (3). The sealing element is at least partly guided by a leaf spring (5) surrounded by a scr...

Disclosed herein is a fluid control valve (24) comprising a valve seat (220), and a nozzle (224) proximate the valve seat (220). The nozzle (224) includes a convergent section (302) and a divergent section (306) formed by a circular segment-shaped profile....

In a vent valve structure including a cut valve (20) that shuts off the flow of fuel vapor and fuel liquid, a positive pressure adjustment valve (30) that opens when positive pressure is applied, and a negative pressure adjustment valve (40) that opens whe...

An improved regulator valve 10 for controlling the purging of fuel vapors collected in a canister 12 and an evaporative emission control system into an intake system 18 of an internal combustion engine employs a solenoid valve assembly 40 with an armature ...

A flow control valve (100) with a reduced number of parts and with few restrictions on installation space is provided. A back pressure chamber (29) of a diaphragm-type valve (21) body communicates with a communication port (23) through a vent hole formed i...
