Abstract

Liquid gas, eg LPG, CNG, LNG or hydrogen, is supplied under high pressure to the inlet 10 whence it enters a first chamber 1 in which it is vaporised and depressurised. The vapour passes through apertures 8 to a second chamber formed in an adjustment pin 7 that sits in a seat and is adjusted to a known pressure, eliminating the need for a diaphragm and spring system. The vapour then passes to a sleeve aperture 6 in which there is a plunger 5 actuated by a stepper motor 25 under the control of a computer connected to a combustor, eg i.c. engine, so that the plunger 5 regulates flow of vapour to the outlet 23. The body 2 may be heated electrically, eg by heating element 24.

Description

VAPORISER REGULATOR
DESCRIPTION
VAPORISER REGULATOR
The present Invention relates to the apparatus and method for the vaporising of fluids and the regulation of gases for fuels supplied to a combustor and more particularly (though not exclusively) is concerned with the delivery of gases Liquid Petroleum Gas, Compressed Natural Gas, Liquid Natural Gas and Hydrogen Gas fuels supplied to the internal combustion engines.
Various systems have been proposed which purport to improve the performance and safety by vaporising fluid fuels and regulating gases.
Various systems use rubber or equivalent diaphragms or springs to control the vaporization and pressure and use water or fluid to heat the apparatus to aid vaporization as known, e.g. from Patent Applications Numbers EP0077286, GB2088475 and FR2801643 The present invention seeks to provide an apparatus and method whereby such aims may be more readily achieved to ensure satisfactory trouble free engine operation.
The present invention seeks to provide the vaporiser regulator with an electrical heating element (24) in the main body (2) is a continuous and controlled heat for the purpose of not having to connect into a water supply on a combustor therefore the fitting of the system is made easier with a reduction in fitting time.
This system will ensure that at all times that there is no icing of the vaporiser regulator device due to the rapid heating element (24) being embodied in the main casing (2) This will stop icing at low ambient temperatures. By
VAPORISER REGULATOR
DESCRIPTION
The liquid gas or gases is supplied under high pressure from a pressure reservoir to the inlet ( 10) of the vaporiser regulator where it enters the first chamber (1) where it is vaporised and depressurised. Regulated to a known pressure this is achieved by pin (7) that is adjustable and is set to a known pressure which eliminates the need for a diaphragm and spring system.
The liquid gas or gases enter the device at the inlet (10) it then enters chamber one (1) where it is heated and rotated around the chamber limiting the need for a diaphragm. The vapour is then conducted through to apertures (8) to chamber two (7) which is also the adjusting pin.
As this is an angular shape it helps with further vaporization and dispenses with the need for a spring and valve.
The adjustment pin (7) is shaped and sits in a matching seat in order that accurate adjustment and pressure regulation can take place. The adjustment is set by a known pressure requirement of the combustor.
The vapours then flow to a sleeve (6) aperture in which there is a plunger (5) that is controlled by a stepper motor (25) that receives an electronic signal from a computer connected to a combustor in order to regulate the plunger to allow the gas vapours to flow to the outlet (23) to fuel the combustor.
This Vaporiser/Regulator will not stop working due to a sticking valve, icing or becoming blocked due to sludge from the vaporization process of fluid gases that leaves sludge to block Jets and pushes on the diaphragms that can alter pressures and over fuel the combustor.

Claims (9)

VAPORISER REGULATOR CLAIMS
1. Apparatus for Fluid and Gas Vaporisation, Regulation and Delivery to a Combustor comprising of an inlet to a first chamber through which fluid and gases flow through to a second chamber through which gases that have been vaporised flow to a sleeve in which there is a plunger controlled by a stepper motor. In use the vaporised gases pass the plunger and the gases flow to the outlet and then fuel the combustor.
2. An Apparatus according to claim 1. The body is heated electronically by an external power supply.
3. An Apparatus according to claim 1. The first chamber which allows the fluid and gases to rotate the flow through the first chamber to pass to the second chamber as a vaporised gas.
4. An Apparatus according to claim 1. The second chamber is an adjustable pin with formed angles and further initiates vaporization and has a pointed end that sits in a matching seat that can be adjusted to allow the regulated pressure to the sleeve to the plunger.
5. An Apparatus according to claim 1. The sleeve is a vertical cylinder with a plunger that is connected to a stepper motor.
Thesleeve is connected to chamber two, as in claim 2. The plunger is lifted by the stepper motor to allow vaporised fluid gases to the outlet. The outlet is connected to the combustor as in claim 1.

Applying an electrical signal from the combustor will allow the plunger connected to the stepper motor to open or close as needed for the vaporised gases to flow to the combustor.
9. A method of vaporising and regulating a fluid, where the fluid is vaporised and regulated by passing through a fluid vaporising and regulating device as claimed in any previous claim and where the control means is supplied with a signal representative of the demand of apparatus consuming the vaporised and regulated fluid.
