A standby generator includes an engine including an output shaft, an alternator, and an enclosure including a base and a number of walls extending from the base including a front wall, a rear wall, a left wall, and a right wall. The output shaft extends toward the alternator and the left wall. The standby generator includes an intake opening configured to allow air to be drawn into the enclosure and an exhaust opening configured to allow heated air and exhaust gases to be expelled from the enclosure. The intake opening is provided on the rear wall and the exhaust opening is provided on the front wall.

A pulsation damper is disposed within a fluid volume defined by a fluid volume wall such that the pulsation damper is exposed to pressure pulsations within the fluid volume. The pulsation damper includes a pulsation damper first half having a first damper wall which is flexible in response to the pressure pulsations; a pulsation damper second half having a second damper wall which is flexible in response to the pressure pulsations; and a damping volume defined between the pulsation damper first half and the pulsation damper second half such that the damping volume is fluidly segregated from the fluid volume. One of the pulsation damper first half and the pulsation damper second half defines a spacing member which maintains separation between the fluid volume wall and one of the first damper wall and the second damper wall.

A silencer includes: a housing that has a draw-in portion drawing in fluid, and a plurality of sound attenuating portions arranged in a flowing direction of the fluid; a first partition provided with an intermediate communicating portion communicating the most downstream attenuating portion with the adjacent attenuating portion located adjacent to the most downstream attenuating portion; a valve portion disposed in the most downstream attenuating portion, the valve portion being capable of closing the intermediate communicating portion; a valve holding portion holding the valve portion, the valve holding portion being detachably attached to the housing; and a draw-out portion provided in a portion of the most downstream attenuating portion other than the valve holding portion, the draw-out portion drawing out the fluid from the most downstream attenuating portion.

A compressor assembly having a compressed gas tank having a tank dampening device in the form of a vibration absorption member. The vibration absorption member can provide a pressure to a portion of the compressed gas tank. A method of controlling sound emitted from a compressor assembly, by using a vibration absorber which exerts a force upon the compressed gas tank. A means for controlling the sound level of a compressed gas tank by using a means for absorbing vibration from the compressed gas tank which exerts a pressure on a portion of the compressed gas tank.

An electric compressor includes a compression part configured to compress fluid, an electric motor configured to drive the compression part, a housing accommodating the compression part and the electric motor, a soundproof cover covering the housing, and a nameplate attached to the housing and including a predetermined information. The housing includes a protrusion that is a part of the housing and protrudes out of the soundproof cover through a hole formed in the soundproof cover. The nameplate is provided on the protrusion.

A pulsation damper is disposed within a fluid volume defined by a fluid volume wall such that the pulsation damper is exposed to pressure pulsations within the fluid volume. The pulsation damper includes a pulsation damper first half having a first damper wall which is flexible in response to the pressure pulsations; a pulsation damper second half having a second damper wall which is flexible in response to the pressure pulsations; and a damping volume defined between the pulsation damper first half and the pulsation damper second half such that the damping volume is fluidly segregated from the fluid volume. One of the pulsation damper first half and the pulsation damper second half defines a spacing member which maintains separation between the fluid volume wall and one of the first damper wall and the second damper wall.
