Gas line (44) to the burner contains a check valve (62) and an accumulator (64) downstream of the check valve.

The check valve assembly (25) is designed for service accessibility without having to dismantle the intensifier.

the fuel tank, controls the pressure in the fuel rail.

A check valve (178) is provided to prevent back flow in the outlet (176) of the second pump (124).

A bent axis pump/motor includes a back plate positioned within a casing, and a check valve positioned in the back-plate, the check valve configured to control passage of fluid from within the casing to an interior of the back plate.

The one-way monitoring valve, downstream from the collecting chamber, may be formed as a duckbill valve of elastomeric rubber having an exit slit at the dispensing end.

Identifying the permissible internal leak rate for a valve has to be one of the top priorities when choosing the correct steam control valve.

The invention concerns a fluid flow control valve providing a simple and economical solution to ensure fast and efficient maintenance not requiring dismantling of the entire valve, nor its fluid supply.

When an elapsed time in the fully closed state reaches a specified time Tc, the proportional control valve is fully opened forcibly.

A Class IV steam control valve will maintain a long operational life.

The inhaler comprises, in general, a housing (20) having an air intake (15), an air flow-control/check-valve (180), a mixing section (30) and a mouthpiece (40).
