A wind energy to compressed fluid conversion system has a compressor to compress fluid when the wind energy exceeds a capacity limit of the generator. Instead of trimming blades to create mechanical spillage, excess energy is converted and stored, and can furnish power when the generator experiences a capacity vacancy.

A method for producing a water-hydraulic machine having a first member (1) and a second member (2) in sliding contact with a contact surface (3) of the first member (1), wherein the second member (2) comprises a surface made of a friction reducing plastic material and the contact surface (3) is a metallic surface, is disclosed. The machine should have a low risk of damages. To this end, the method includes the steps of using a first member (1) comprising a first part (4) having the contact surface (3) and a second part (5), using a high temperature hardening process at a temperature of at least 1000 C. to give a deep surface hardening of the contact surface (3) of the first part (4), machining of the first part (4) to the desired geometry, assembling the first part (4) and the second part (5) to form the first member.

A control valve and a variable capacity compressor which are capable of preventing an unnecessary loss of control gas to improve efficiency of the compressor reduces loss of control gas by eliminating a fixed orifice hole in an existing valve assembly and forming it in a control valve or a passage connecting the control valve and a crank chamber. The size of the fixed orifice hole is variable (which is possible by selectively opening and closing a plurality of holes) depending on the operation of the compressor. On the other hand, forming the fixed orifice hole in the passage connecting the control valve and the crank chamber causes the loss of control gas to be reduced because the fixed orifice hole can be machined to a smaller size compared to an existing orifice hole, the minimum size of which is limited due to difficulty of machining.

An electronic control valve for an HVAC system of a vehicle may include, in the electronic control valve configured to control the angle of a swash plate (angle with respect to the surface perpendicular to a rotation shaft of a compressor) in the compressor in an HVAC system, a solenoid, a plunger coupled to the solenoid member and configured to slid according to whether the solenoid is magnetized, a valve body formed integrally with the plunger, and configured to open or close a supply flow path through which a fluid flows into the compressor, a discharge flow path through which a fluid is discharged from the compressor, and a control flow path through a fluid flows to control the angle of the swash plate mounted inside the compressor, a diaphragm configured to operate the plunger by the pressure of refrigerant, and a return spring configured to return the plunger, and the solenoid is applied with power according to a vehicle target cooling load.

The present invention relates to a suction pulsation reducing device of a swash plate type compressor, and more particularly, to a suction pulsation reduction apparatus provided on a suction channel formed in a rear head of a swash plate type compressor, in which a moving range of a core portion is limited and all parts to be mounted on a suction channel are integrally formed in a case.

A variable displacement swash plate type compressor includes a first and a second valve body, and a suction and a bleed window. An open degree of the suction window is minimized by the first valve body and an open degree of the bleed window is maximized by the second valve body when a suction pressure is lower than a predetermined suction pressure and a crank chamber pressure is higher than a control pressure. The open degree of the suction window is increased and the open degree of the bleed window is maximized when the suction pressure is higher than the predetermined suction pressure and the crank chamber pressure is higher than the control pressure. The open degree of the suction window and the open degree of the bleed window are decreased when the crank chamber pressure is lower than the control pressure.

A device and method for extending the lifespan of a shaft seal for an open-drive compressor is provided. The device and method can also reduce and/or prevent deterioration of the shaft seal regardless of the operation condition of the open-drive compressor. The device and method can further reduce and/or prevent leakage of a lubricant and/or refrigerant that can cause deterioration of components within a transport refrigeration unit (TRU).

The invention relates to a swashplate (5) for a swashplate compressor (1) comprising a main swashplate body (8), which is made from a sintering material, and to a method for producing the swashplate (5).
