Abstract:
Device for converting reciprocating motion into rotary motion and vice versa, in axial-piston mechanical systems The invention relates to a highly efficient device for converting the reciprocating motion of the pistons into rotary movement of the shaft and vice versa in the axial-piston, mechanical systems of engines, pumps and compressors, which has an increased contact resistance to the power load, and makes it possible to increase several times the torque, as a result of a shorter kinematic chain and overcoming the kinematic constraints on the torque of the output shaft that are created by the working stroke of the pistons. Four types of the Device have been developed, where the kinematic chain in two of them has three links, and in the other two - four links, finding application respectively in the structures of hydraulic motors and pumps, and internal combustion engines. The Device is also used in air piston compressors, and can be used in all other devices that include mechanisms for converting a reciprocating motion into rotary motion and vice versa.

The connector may also be used by the compressor assembly as a heat sink, inlet, mount, filter, and/or to provide other functions that improve the operation of compressor assembly.
Abstract:
A mechanism 21 for converting rotating motion to rotating and reciprocating motion and/or vice versa. The mechanism has a housing or support 22, a first member 23 rotatable about a first axis and reciprocable along the first axis, and a second member 2 rotatable about a second axis spaced from the first axis. Rotation of the first member 23 or the second member 25 causes rotation of the other member. A guide 29a, 29b is configured to contact a cam surface 27a, 27b. The cam surface or the guide is provided on the first member 23. The cam and guide are configured to cause the first member 23 to rotate upon movement of the first member along the first axis, or to move along the first axis upon rotation of the first member 23.

Abstract:
Provided are various devices and processes that harness the inherent kinetic energy of a flowing pressurized fluid to drive a compressor to compress a fluid without any need for electrical or chemical energy. The flowing drive fluid flows over a boundary layer disk turbine, or Tesla turbine, which is mechanically coupled to a compressor that compresses a fluid. The flowing fluid may be a natural gas from a hydrocarbon recovery operation. The compressed fluid may be air that is used to power a pneumatic device in an industrial process. Harnessing the kinetic energy of the flowing fluid increases economic efficiency of the process, while also avoiding unwanted emissions adverse to the environment and public health.

A tire inflation system including a drive mechanism having a rotational axis, a pump cavity positioned a radial distance away from the axis of rotation, and a force translator coupling the rotational axis to the pump cavity. The drive mechanism includes a cam comprising an arcuate bearing surface having a non-uniform curvature, the cam rotatable about the rotational axis, and an eccentric mass couple to the cam that offsets a center of mass of the drive mechanism from the rotational axis. The pump cavity is rotatably coupled to the cam, wherein the pump cavity includes an actuating element and a chamber. The force translator couples the arcuate bearing surface to the actuating element, wherein the force translator includes an axis having an arcuate position fixed to an arcuate position of the pump cavity.
Abstract:
Reciprocating compressors for the oil and gas industry with a timing valve and related methods are provided. A reciprocating compressor 100 has a chamber 110, a timing valve 150, an actuator 160 and a controller 170. A fluid entering the chamber 110 via a suction valve 130 is compressed inside the chamber, and evacuated from the chamber via a discharge valve 140. The timing valve is located between the chamber and a fluid volume at a relief pressure that is lower than a pressure in the chamber when the timing valve is opened. The actuator is configured to actuate the timing valve. The controller is configured to control the actuator such that to open the timing valve during an expansion phase of the compression cycle, and to close the timing valve when the relief pressure becomes equal to the pressure in the chamber or when the suction valve is opened.
