GB2456521A - Chain oiler - Google Patents

Abstract

The oiler comprises a reservoir attached to the main body of the vehicle, e.g. a motorcycle, and refillable via a filler tube, with a breather tube to allow air expulsion. The reservoir feeds a valve comprising a seat supporting a spring-biassed valve ball. When the vehicle is in motion, bumps, undulating ground surfaces &c cause the ball to lift to release oil down a feeder tube (which can be cut to size) to the chain.

Title: Momentum Chain Oiler

Background:

Summary description

This is a chain oiler for motorcycles or other motor / chain driven vehicles.

Existing problem

This oiler will solve the common problem on all chain driven vehicles where chains and sprockets become worn, damaged and would require replacement.

How it works

This oiler uses the vehicles momentum of up and down motion from the surface over which it is used e.g. uneven surfaces (even the undulation of road surfaces). The valve is situated at the rear of the vehicle on the swing arm next to the rear wheel. The vehicle would go over a bump and the valve would open and close to let a bit of oil pass down to the chain.

Features:

The key features are:

• Gravity-fed - responds to the varying terrain

• No wearing parts

• No specialist connections (including electrical or vacuum) required

• Easy maintenance

• Simple but fully functional

• Can operate with most oil-types - from light-oil to car engine oil, including biodegradable types

Drawings:

Drawing 1: Shows end to end functionality, from the oil reservoir and filler tube, to the feeder tube onto the chain.

Drawing 2: Shows the oil reservoir attached to the vehicle and the mechanism for refilling -via the filler tube with the outlet pipe to the valve oiler.

Drawing 3 / 3a: Shows the valve oiler mechanism. The spherical ring supports the ballbearing thus creating a seal. The spring supplies pressure to the ball bearing keeping it sealed when the oiler is not in motion. Additionally shows the outlet tube to the chain feeder tube.

Drawing 4: Shows the chain feeder tube which ultimately provides the lubrication to the chain during vehicle motion.

Claims (1)

1. CLAIMS (Momentum Chain Oiler -January 2008)

   Title: Momentum Chain Oiler Main Technical features:

   • No battery or vacuum connections required unlike other chain-oilers commercially available

   • No other chain-oiler operates in this way (i.e. gravity-fed, responding to the undulation of the road surface)

   • This chain-oiler has no wearing parts

   • This chain-oiler can be completely taken apart and put back together again needing no additional gaskets or seals

   • This chain-oiler could be used on a wide range of chain-driven vehicles, for example;

   o all motorcycles - including motocross, enduro, trials, supermoto, road racing,

   minhmotos, pit bikes, side cars o

   mopeds o

   superbikes o

   speedway o

   grasstrack o

   quad bikes o

   trikes o

   go-karts o

   buggies o

   even bicycles

   • This chain-oiler has been designed to run on bio-degradable oil (but would run on most oil types, from light-oil to engine oil)
