A baffle plate for a compressor, a compressor, and refrigeration apparatus are provided. The baffle plate has a plate body, a through hole and a connection part. The through hole is formed in the plate body. The plate body extends from the through hole in a direction deviating from the axis of the through hole. The connection part is connected with the plate body and is used for connecting the plate body to a non-rotating member. A fixed baffle plate is arranged in the compressor, to physically block the gas flow and form a space for stabilizing the refrigerant oil or lubricant oil on one side of the baffle plate corresponding to the oil sump. The space can isolate the disturbance from spiral flow of a lower cavity to the oil sump caused by the rotation of the motor when the compressor operates.

A lower end plate cover is provided with a bulging portion. In a circumferential direction of a rotary shaft, a plurality of bolt holes includes a first bolt hole arranged between a distal end portion and a proximal end portion of the lower discharge valve, a second bolt hole arranged in a position adjacent to the first bolt hole on a side close to a lower vane groove with respect to the first bolt hole, and a third bolt hole arranged in a position adjacent to the first bolt hole on a side away from the lower vane groove with respect to the first bolt hole. When the bulging portion is divided into a first bulging portion and a second bulging portion using a first straight line, the first bulging portion is larger than the second bulging portion.

[Problem] A scroll compressor is provided which is capable of effectively reducing a pressure loss in a pathway extending from a discharge space to a discharge port. [Solution] The scroll compressor includes a discharge space 27 formed in a compressing mechanism cover 9 of a housing 11, a discharge hole 26 which is formed in a fixed scroll 21 and discharges a compressed refrigerant to the discharge space, a discharge port 51 which discharges the refrigerant to the outside of the housing, a relief passage 71 which communicates the discharge space and the discharge port with each other, and a differential pressure valve 74 which is provided in the relief passage and opens in accordance with a pressure difference between the discharge space and the discharge port. The relief passage opens in the discharge space above the discharge hole.

A shunt pulsation trap for a positive-displacement gas-transfer machine having a gas transfer chamber with an intake port and a discharge port and having at least one positive-displacement drive device (such as two cooperating rotors) defining a compression region of the transfer chamber. The trap includes a pulsation-trap chamber arranged for parallel fluid flow with the machine transfer chamber. The trap has a first (e.g., inlet) port in communication with the compression region of the transfer chamber (e.g., at least one lobe span away or totally isolated from the transfer-chamber intake port), a second (e.g., discharge) port in communication with the discharge port of the transfer chamber, and at least one pulsation dampener in the pulsation-trap chamber. In this way, the shunt pulsation trap traps and attenuates gas pulsations before discharge from the machinery transfer chamber, thereby reducing induced NVH and improving machinery efficiency.

The invention relates to a vacuum pump (1) for a motor vehicle, comprising a pump housing surface (8), on which a noise reduction hood (30) delimiting a sound damping volume is mounted. The invention is characterized in that the noise reduction hood (30), on at least one inner surface facing the pump housing surface (8), has a three-dimensional sound dissipation structure (60).

A vacuum pump of a vehicle for reducing operation noise may include a rotor rotating in a space defined by a housing formed in a pump body at an eccentric position relative to a center of the space, a vane installed to the rotor to rotate eccentrically in the space, and an oil outlet passing through the pump body and formed at a predetermined height above a lower limit of the space such that, when lubricant in the space is discharged in a pressurized state by the vane, the lubricant is not reintroduced back into the space by gravity.

A compressor and a method for assembling a compressor are provided. The compressor may include a compressor casing coupled to each of a suction inlet, into which a refrigerant may be introduced, and a discharge outlet, through which the refrigerant may be discharged, a compressor body mounted inside the compressor casing to compress the refrigerant suctioned in through the suction inlet, and then discharge the refrigerant through the discharge outlet, a noise reducing member disposed between the compressor body and the compressor casing, and at least one fixing member mounted inside the compressor casing to fix the noise reducing member to an inner wall of the compressor casing.

A compressor includes a compression mechanism drawing in, compressing and discharging fluid and a housing accommodating therein the compression mechanism. The housing has therein a discharge chamber into which the fluid compressed by the compression mechanism is discharged. A silencing and cooling device is provided in the discharge chamber to cool the fluid discharged in the discharge chamber and reduce pressure fluctuation. A dispersion wall is provided in the discharge chamber on downstream side of the discharge chamber that is opposite from an inflow port with respect to flowing direction of the discharged fluid. The dispersion wall is disposed to cover a part of the silencing and cooling device and cover at least a part of the inflow port.
