Appl. No.:

11/486460

Inventors:

Bernard Wiesen - Great Neck NY, US

International Classification:

F01L 3/20

US Classification:

123200, 123 65 V

Abstract:

This invention relates to novel reciprocating shuttle inlet valves, effective with every type of two-cycle engine, from small high-speed single cylinder model engines, to large low-speed multiple cylinder engines, employing spark or compression ignition. Also permitting the elimination of out-of-phase piston arrangements to control scavenging and supercharging of opposed-piston engines. The reciprocating shuttle inlet valve () and its operating mechanism () is constructed as a single and simple uncomplicated member, in combination with the lost-motion abutments, () and (), formed in a piston skirt, obviating the need for any complex mechanisms or auxiliary drives, unaffected by heat, friction, wear or inertial forces. The reciprocating shuttle inlet valve retains the simplicity and advantages of two-cycle engines, while permitting an increase in volumetric efficiency and performance, thereby increasing the range of usefulness of two-cycle engines into many areas that are now dominated by the four-cycle engine.

Abstract:

Synthetic sponge or other resilient material is joined to the top of a room air-conditioner to absorb the physical impact of rain and dripping water to inhibit the creation of the noise that would otherwise occur. Additionally, a buffer formed with angular surfaces, to absorb and deflect the full impact of rain and dripping water to inhibit the creation of noise that would otherwise occur.

Appl. No.:

8/334552

Inventors:

Bernard Wiesen - Great Neck NY

International Classification:

F02B 7526

US Classification:

123 51R

Abstract:

A highly pressurized internal combustion engine, wherein arrangements to balance the intake flow of air that passes from the turbochargers to a windchest, through spring valves to compressor cylinders, that force the charge into a pressure chamber to supply an equally divided amount of charge air to the power cylinder ports that are controlled by the movements of the power pistons, with provisions to cool the air charge within the engine block coolant jacket. The bottom of the compressor pistons are employed to pump oil mist into and out of the bottom of the compressor cylinders to cool and lubricate the power pistons. A simple oil cooler surrounds the engine shaft where it passes through the cylinder block coolant jacket.

Inventors:

Bernard Wiesen - Great Neck NY

International Classification:

F02F 700

US Classification:

123195S

Abstract:

Arrangements are disclosed for a lightweight engine frame wherein weight reduction and manufacturing simplicity are obtained primarily through the use of skeletal box frames fabricated from extruded material joined at their ends forming a unique double lap joint assembly without the need for additional components. The disclosure describes the inventions advantageous corner construction which permits simple assembly with a minimum of tools. Also the described construction may be combined with a soundproofed exterior shell. Shown is an engine of the axial type, but similar constructions may be employed for other engine types, as well as transmission cases and where precise frame structures are required and the use of this invention may be an economic alternative.

Appl. No.:

7/617362

Inventors:

Bernard Wiesen - Great Neck NY

International Classification:

F02B 7526

US Classification:

123 58B

Abstract:

This invention relates to internal combustion engines in which the cylinders are arranged parallel to the main shaft and the reciprocating movements of the pistons are converted to rotation by means of a swashplate, and more particularly to means for automatically varying the combustion chamber volume to get at all times the maximum combustion chamber pressure permissible. Various embodiments of the invention are shown and involve changing the compression ratio by the controlled movements of a fluid under the action of the gas pressure in the combustion chambers. The movement of the fluid being controlled variously and in combination by check valves, spring loaded discharge valves and discharge orifices arranged and adjusted to give the required changes in position in accordance with the engine load with the use of spring pressure to maintain a balanced condition in the various arrangements.
