Improvements relating to the lubrication of compressed air selfstarting and braking apparatus for internal combustion engines

163,203. Edington, H. April 24, 1910. Force-feed lubricating for compressed-air selfstarting and braking apparatus for internalcombustion engines of the type described in Specification 24006/14, [Class 7 (v), Internalcombustion engines, Starting &c.]. A lubricantreservoir 1 is arranged below the compressormotor. A passage 5 establishes communication between the reservoir and the air delivery-port 6, and a pipe 7 connects the lower part of the reservoir with an injection port 8 situated between the delivery port 6 and the inlet port 9. A check-valve 12 is inserted in the pipe 7 to prevent leakage of air by way of the port 8, when compressed air enters the port 9. Alternatively, a check-valve may be inserted in the passage 5. When the apparatus acts as a compressor or is running idle, lubricant is forced past the valve 12 into the cylinder 2 by air pressure from the delivery port 6. Surplus lubricant drains to the reservoir through the passage 5. No lubricant is supplied to the cylinder when the apparatus functions as a self-starter. Plugs 16, 18 are provided for filling and draining the reservoir. The invention may be applied to compressor-motors having more than three blades.

PNEUMATIC STARTER FOR INTERNAL COMBUSTION ENGINE

PNEUMATIC STARTER FOR INTERNAL COMBUSTION ENGINE A starter arrangement for an engine includes a fluid actuated rotary vane motor which is adapted to engage an associated engine. The rotary motor has a plurality of blades or vanes with each of the blades being made from a fiber reinforced plastic material to reduce friction. A sleeve, in which the rotary motor is positioned, has on its inner surface a hard metallic coating to reduce friction. A relay valve member selectively provides a pressurized operating fluid to the rotary motor. The blade material and the sleeve inner surface coating cooperate to enable the vane motor, when it is actuated by the relay valve member, to rotate in the sleeve with a minimum of friction thereby obviating the need for a lubricating agent.

LOW TEMPERATURE STARTING SYSTEM FOR INTERNAL COMBUSTION ENGINES

LOW TEMPERATURE STARTING SYSTEM FOR INTERNAL COMBUSTION ENGINES The system is based on incorporating a start preturbine (80) capable of injecting pressurised air in the inlet manifold (10) of the motor (2). The preturbine (80) is driven by air supplied by a storage reservoir (68) and starts operating after an air starter motor (46) has been actuated. Operation is continued until, as a result of the ignition of the fuel, the engine (2) attains a high speed, after which the starter motor (46) and the preturbine (80) are disengaged, whereby the engine decelerates. When the engine reaches a preset low speed, the preturbine (80) is reengaged and stages of operation of the preturbine (80) coinciding with engine acceleration alternate with inoperative stages coinciding with engine deceleration until an engine speed above the low speed is maintained. A electronic sequencer (90) controls the successive operations. Figure 1.

A METHOD AND APPARATUS FOR STARTING AN ENGINE UTILIZING UNIT VALVE ACTUATION

AIR STARTER

A pneumatically operated starter having a combination pistonvalve, located in a first chamber downstream of the usual on-off valve, that throttles the starter to a low speed initially in its closed position and as air is supplied opens in response to the air pressure and simultaneously engages the starter pinion with the engine ring gear and upon further engagement of the starter pinion allows air to freely pass and accelerate the starter. Upon the starting of the engine, the piston-valve is automatically returned to its initial position by a combination of mechanical helical pinion throwout, spring return and latching pressurization of a second chamber behind the piston-valve. Latching pressurization is accomplished by a second valve admitting air pressure behind the piston-valve in response to a pressure signal developed in the starting cycle. The air supply may then be shut off manually to stop the throttled rotation of the starter and to reset the second valve controlling the latching pressurization of the chamber behind the piston-valve to ready the starter for the next starting cycle.

Spring means biases the piston and valve head toward the valve seat so that the flow path is normally closed to fluid flowage therealong. Increased fluid pressure in the control chamber acts on the piston to open valve and thus the flow path, and comparatively high pressure downstream of the valve seat raises the pressure in the reaction chamber to force the valve head against the valve seat to prevent upstream flowage of the gases creating the high downstream pressure.

Drivetrain for use in e.g. industrial truck, has fluid motor comprising non-uniform torque curve, where non-uniformity of torque of fluid motor is adjusted to non-uniformity of starting torque of engine

The drivetrain (1) has a fluid pressure storage (8) provided for a combustion engine (2), where the combustion engine comprises a rotational torque coefficient for starting cyclic variation exhibiting start rotational torque at a crankshaft (5). A fluid motor (7) i.e. hydrostatic motor or pneumatic motor, comprises a non-uniform torque curve, where non-uniformity of the torque of the fluid motor is adjusted to the non-uniformity of starting torque of the engine. The fluid motor produces increased rotational torque over rotational angle in a reduced angle of rotation. The fluid motor is designed as an axial-piston motor, inner-acted upon radial piston motor or outer-acted upon radial piston motor.

Pneumatic system for piston engine

Pneumatic starter for internal combustion engine

A starter arrangement for an engine includes a fluid actuated rotary vane motor which is adapted to engage an associated engine. The rotary motor has a plurality of blades or vanes with each of the blades being made from a fiber reinforced plastic material to reduce friction. A sleeve, in which the rotary motor is positioned, has on its inner surface a hard metallic coating to reduce friction. A relay valve member selectively provides a pressurized operating fluid to the rotary motor. The blade material and the sleeve inner surface coating cooperate to enable the vane motor, when it is actuated by the relay valve member, to rotate in the sleeve with a minimum of friction thereby obviating the need for a lubricating agent.
