Abstract
An arrangement comprising a vane pump/motor, operatively connected between a rotating part and an accumulator 3, is operated as a pump when driven by the rotating part to convert kinetic energy of the rotating part into potential energy of compressed air which is pumped into the accumulator 3 during braking, and is operated as a motor when the stored compressed air assists in driving the rotating part during acceleration or start-up. The vane pump/motor comprises a rotor 2 which rotates within a body 1 in the form of a hollow disc having a pair of shutters 6 reciprocally movable within recesses in opposite sides of the body 1 and held in sealing contact with a smoothly changing profile of the rotor 2 by springs 9, creating compression chambers. The shutters 6 are locked in a fully retracted position during a waiting phase between braking and acceleration phases. The arrangement may be used for braking, acceleration and start-up of internal combustion engines, turbines, electric motors or rotating wheels.
Description
BRAKING ACCUMULATOR ACCELERATOR The invention relates to a Braking Accumulator-Accelerator (BAA).
The BAA may be used to accumulate kinetic energy of a wheel moving vehicle during braking in order to use it to accelerate the vehicle during the next acceleration. It allows to save fuel as we ! ! as to cut pollution. The BAA may be also used as a starter for internal combustion engines as well as an accelerator to assist start-up of turbines, electric motors, drives and other devices in which a forced braking of idle rotating parts may be used to accumulate a useful energy of compressed air.
The purpose of this invention is provide a simple and workable device which transformes kinetic energy of rotating parts of a vehicle into kinetic energy of a rotating rotor and into potential energy . of compressed air, stores these energies for a period of time and releases them back to the vehicle to accelerate start-up of its parts.
Accordingly, this invention provides a braking accumulator-accelerator including a body designed as a hollow disc, a rotor rotating inside of the body with at least two halfpistons which fit into an internal cross section of the body, at least one pair of shutters located at opposite sides of the body which are kept in constant contact witll the rim of the rotor by springs or other devices thus creating temporary compression chambers between tlie body, the rotor and the shutters, a receiver which accumulates the air compressed by the rotor when it is driven by rotating parts of a vehicle or other device and which supplies the compressed air back to the body when the rotor drives the rotating parts, valves located at the both sides of the shutters which controls air flou, connecting pipes which connect the body, the receiver and the valves, and a shaft which connects the braking accumulator - accelerator to the rotating parts of a vehicle or other device.
The purpose of the design is also achieved bz some partial distinguishable signs of the invention.
The shutters are locked in their depressed position during a waiting phase.
The disc is designed ith capabilitv to operate as a compressor as well as an air motor.
The shaft is designed with capacity to be connected to the shaft of an internal combustion engine to operate as a starter.
The shaft is designed with capacity to be connected to the shaft of a turbine, an electric motor or other rotating device to operate as a start-up assistant.
. preferred embodiment of the invention will now be described with reference to the accempanying drawings in which :
FIGURE 1 shows a front view of the whole BAA.
FIGURE 2 is a cross section of the BAA through plane A-A.
FIGURE 3 shows positions of the shutters and the valves at a braking phase.
FIGURE 4 shows positions of the shutters and the valves at a waiting phase.
FIGURE 5 shows positions of the shutters and the valves at a phase of releasing the accumulated energy.
FIGURE 6 shows positions of the shutters and the valves at the idle phase.
-\s shown in Fig. 1, the BAA has the body 1 with the shape of a hollow disc. Inside of the body the rotor 2 is located with its maximum cross section to coincide with maximum cross section of the body pair of shutters 6 is located on opposite sides of the body 1 and can protrude into the body 1 keeping in constat contact with the rim of the rotor 2 by force of the springs 9 thus creating temporary compression chambers. Forced by the rim of the rotor 2, the shutters 6 can recess back into depression of the body 1. The half pistons 11 are located at the rim of the rotor 2 to insure compression in the compression chambers created between the shutters 6 and the half pistons 11. The half pistons 11 act as cams by their smooth outer profiles depressing the shutters 6 into the body 1. On the both sides of the shutters 6 the valves 5 are located to provide intake or discharge of air. The receiver 3 is connected to the body 1 by pipes 4 through valves 5.
Fig. 2 shows a cross section of the BAA along the plane A-A at the moment when the half pistons 11 of the rotor 2 are passing under the shutters 6. The shutters 6 are full depressed into the body 1 boy the rim of the rotor 2. The half piston rings 12 secure compression between the half pistons 11 and the body 1 while the seal profiles 8 secure compression between the side surface of the rotor 2 and the body 1. The space between the seal profiles 8 at one side of the rotor 2 is filled with a lubrication oil. The left side of the shaft 7 is connected to the wheels of a vehicle or to rotating parts of a device through a clutch which connects or discotmects the shaft 7 from them.
The BAA works in the following way.
At the beginning of braking the shait 7 is connected to wheels of a vehicle or rotating parts of a device and the rotor 2 begins to rotate anticlockrvise. A braking phase begins.
Fig. 3 shows positions of the valves 5 at a braking phase.
With the movement of the rotor 2 anticlockwise a negative pressure is created in the left low compression chamber 13. The valves 5 of the left low compression chamberl3allow ambient air to enter to the chamber but close the pipes 4 which connect the left low compression chamber 13 to the receiver 3. ambiant air is sucked to the left low compression chamber 13.
With the movement of the rotor 2 anticlockwise a positive pressure is created in the right low compression chamber 16. The valves 5 of right low compression chamber 16 allow compressed air to come through pipes 4 to the receiver 3 but close the pipes 4 which connect the right low compression chamber 16 to ambient atmosphere. The compressed air is accumulated in the receiver 3.
With the movement of the rotor 2 anticlockwise a negative pressure is created in the right top compression chamber 15. The valves 5 of the right top compression chamber I ? allow ambient air to enter to the chamber but close the pipes 4 which connect the right top compression chamber 15 to the receiver 3. Ambient air is sucked to the right top compression chamber 15.
With the movement of the rotor 2 mticlockv ise a positive pressure is creat d in the left top compression chamber 14. The valves ? of left top compression chamberl4 allow compressed air to come tlrouDli pipes 4 to the receiver 3 but close the pipes 4 which connect the left top compression chamber M to ambient atmosphere. The compressed air is accumulated in the receiver 3.
At the braking phase the BAA works as a air compressor. Air pressure is growing in the receiver 3 during the braking phase. Kinetic energy of a vehicle or rotating parts is accumulated in the receiver 3 as potential energy of compressed air and in the rotor 2 as kinetic energ of a rotating rotor. At the end of the braking phase when the wheels of the or rotating parts stop, the shaft 7 is disconnected from them.
Fig. 4 shows positions of the valves 3 at a waiting phase.
All valves 5 are closed. The shutters 6 are locked at their full depressed position. The rotor 2 is rotating under rotary inertia or stationary. Pressure in the receiver 3 is maximum and constant.
Fig. 5 shows positions of the valves 5 at an acceleration phase.
With a command to start, the shaft 7 is connected to wheels or rotating parts.
The valves 5 of the left low compression chamberl3allow compressed air of the receiver 3 to enter to the compression chamber 13 through pipes 4 but close the pipes 4 which connects the left low compression chamber 13 to ambient air. The compressed air of the receiver 3 starts to rotate the rotor 2 and by so-the wheels or rotating parts.
The valves 3 of the right low compression chamberl3allow depleted air to exhaust but keep closed the pipes 4 which connect the right low compression chamber 13 to the receiver 3.
The valves 5 of the right top compression chamber 15 allow compressed air of the receiver 3 to enter to the compression chamber 15 through pipes 4 but close the pipes 4 which connect the right top compression chamber 13 to ambient air. The compressed air of the receiver 3 starts to rotate the rotor 2.
The valves 3 of the left top compression chamber 14 allow depleted air to exhaust while keeping closed the @ pipes 4 which connect the left top compression chamber 14 te the receiver 3.
At the acceleration phase the B orks as an air motor. Air pressure is decreaqing in the receiver 3 during the braking phase. Kinetic energ : of the rotating rotor 2 and potential ellergy of the air compressed in the receiver 3 accumulated during the braking phase are transformed back into kinetic energy of a vehicle or rotating parts. At the end of the acceleration phase the shaft 7 is disconnected from wheels or rotating parts.
Fig. 6 shows the BAA at an idle phase when it is not in use. The valves 3 are opened, pressure at thv receil er S is ambient one, the rotor 2 is stationary.
With a new brake. the above phases are repeated.
The above show n design of the BAA exercises two strokes in each of the two compression chambers-a working stroke and a ex as stroke. With different number of the half pistons 11, the shutters 6, the valves 3 and the pipes 4 the number of the compression chambers may be different.
Several bodies like body 1 may be assembled on a single axis thus creating a multiple BAA.
