The purpose of the present invention is to provide an inverter-integrated electric compressor that has improved inverter device assemblability with respect to a housing, allows for improved productivity and reduced manufacturing costs, and allows an inverter device, and thus the electric compressor itself, to be made more compact and lightweight. Provided is an inverter-integrated electric compressor (1), wherein an inverter device (7) is provided with a resin structure (12) formed as a single unit with a housing section for high-voltage system components and a circuit board assembly section, and by assembling a power system circuit board, a control system circuit board (15), a busbar, a plurality of high-voltage system components that make up the inverter device (7), and the like onto the resin structure (12), the inverter device (7) is made into a unit (34) and this unit (34) is assembled onto and integrated with the inverter housing section (8).

A sealed compressor housing includes a tubular top cover and a tubular lower housing each with an elliptical horizontal cross section that can be snap-fitted together. Major and minor axial centerlines of the top cover and the lower housing respectively coincide with each other. A terminal pin is provided on the lower housing and is disposed axially symmetrical about a centerline of the terminal pin. A portion of the top face on the side of the terminal pin and a front side of the top face are higher than a rear side thereof. A bottom outer surface of the lower housing has a smooth ellipsoid shape. An angle is formed between the centerline of the terminal pin and the major axial centerlines.

An air compressor includes a cylinder being fitted with a piston body and an air storage container formed integrally with the cylinder The air storage container defines therein an air chamber having a diameter greater than or equal to the inner space of the cylinder A pressure relieving mechanism is directly mounted to the air storage container rather than at one outlet provided at the air storage container, wherein one portion of the pressure relieving mechanism is located in the air chamber of the air storage container while the other portion of the pressure relieving mechanism extends out of the air storage container to be in contact with a push button provided on an external enclosure, whereby a user may depress the push button to reduce the air pressure within the air storage container.

An air compressor includes an air storage container, a cylinder fitted with a piston body and a main frame for mounting a motor. The cylinder and the main frame are integrally formed of plastic. The air storage container is detachably mounted to the cylinder. The main frame is provided with though holes for guiding the air flow, generated by a cooling fan, to flow through the main frame. The main frame is formed with two lateral walls and a bottom wall to form a U-shaped wind collecting shell. The second portion of the main frame is held by multiple radial braces, which facilitates the air flow being introduced through the main frame for rapidly dissipating the heat generated from the reciprocating motion of the piston body, so that the operational security can be increased. The non-metal air compressor may lead to a reduction of the manufacturing cost and the weight.

Disclosed is an air compressor (10) for supplying compressed air to a pneumatic system in a motor vehicle. The air compressor (10) comprises a crankcase (46), a cylinder housing (14) connected to the crankcase, a cylinder head (20), a crankshaft (40) rotatably mounted in the crankcase, a cylindrical piston (12) that is connected to the crankshaft (40) by a connecting rod (42). In order to load the compressed air with as little heat as possible, the crankcase (46), the cylinder housing (14), the cylinder head (20), and the piston (12) are made of aluminum or an aluminum alloy, and the at least one piston ring (54) or the at least one oil ring is made of gray cast iron or polytetrafluoroethylene (PTFE).

A mounting arrangement secures a refrigerator compressor to a support base member through a plurality of elastomeric mounts secured on pin elements with retainers. The mounts include head portions which extend through openings provided in an elongated plate fixed to the compressor. The mounts are specifically formed with a rounded bottom to pre-load the mounting arrangement and prevent vibration transmission through cores of the mounts. In addition, each mount includes a plurality of vertically spaced rings which provide shock protection against a large impact force by deflecting and potentially contacting each other, while normal vertical isolation occurs by deflection of an uppermost one of the rings. The mounts are formed with various undercuts which allow the mounts to be optimized for the mass and operational frequency of the compressor.

A reciprocating compressor includes a cylinder that defines a compressing space and a discharge muffler configured to receive refrigerant compressed in the cylinder and to discharge the refrigerant. The discharge muffler includes a discharge muffler body and a discharge guide supported by the discharge muffler body. The discharge muffler body defines a discharge space configured to receive the refrigerant from the cylinder and includes a wall protruding from an inner circumferential surface of the discharge muffler body. The discharge guide is coupled to the wall and includes a pipe that defines a pipe inflow hole configured to receive the refrigerant from the discharge space and a pipe outflow hole configured to discharge the refrigerant. The discharge guide further includes a fixing bracket that couples the pipe to the discharge muffler body.

The subject of the invention is a suction pump having a suction tube and a suction piston for producing a negative pressure in a negative-pressure retaining device, a set consisting of the negative-pressure retaining device and the suction pump, and a method for attaching the negative-pressure retaining device.

The invention relates to a Direct Current (DC) air conditioning compressor drive unit for use in both buildings and in vehicle installations. Energy savings can be demonstrated in the automotive industry when compared to the current status of known DC air conditioning drive units and in particular those relying on direct or pulley drive. More particularly, when coupled to DC battery and inverter technology for air conditioning purposes within domestic housing, commercial and industrial buildings, it can provide extreme energy savings. Preferably, the purpose of this innovation is to enhance the viability and energy savings opportunities of using DC power in air conditioning if used in conjunction with smart compressor technology.

A 3D-printed oil separation assembly for use in a reciprocating compressor is provided. The compressor includes a suction chamber, a crankcase chamber, and at least one partition member at least partially separating the suction chamber and the crankcase chamber. The at least one partition member further includes at least one opening. The 3D-printed oil separation assembly comprises a coalescing structure positioned within the crankcase chamber adjacent the at least one partition member at the at least one opening; and at least one securing structure secured in operable relation with the at least one demisting structure so as to secure the coalescing structure relative to the opening. The coalescing structure comprises at least one structure selected from the group consisting of a baffled structure, a demisting structure, and combinations thereof. At least a portion of the coalescing structure is 3D-printed.
