摘要： An air compressor improves the dustproof performance of an intake path to a crankcase. The air compressor includes a compression assembly that reciprocates a piston in a cylinder to produce compressed air, a crankcase accommodating the compression assembly and having an inner inlet to allow outside air to be drawn, a filter located in the crankcase and covering the inner inlet from outside, a filter cover having an outer inlet and covering the filter from outside, and a dust cover covering the filter cover from outside, covering the outer inlet, and including an outer circumferential portion. The outer circumference portion and the filter cover have a space to draw outside air between the outer circumference portion and the filter cover.

摘要： A reciprocating pump includes a fluid section that includes fluid-displacing members and a power section that includes crossheads coupled to a respective fluid-displacing member. The power section actuates the fluid section by actuating the crossheads through respective crosshead bores formed through the power section. The power section also includes structural members, pairs of support plates, and pairs of arcuate crosshead sections secured in place between the structural members against a respective pair of support plates. Each pair of the arcuate guide sections comprises a top section and a bottom section that form a portion of a respective crosshead bore. Each pair of the arcuate crosshead guide sections are also secured in place using clamping segments secured to edges of windows of the structural members by bolts extending through interior passages of the clamping segments and having threads that mate with threaded holes extending into the edges of the windows.

摘要： A crankcase heating control system for a heat pump system includes a data receiving module and a power control module. The data receiving module receives data indicative of a temperature of a compressor of the heat pump system, data indicative of an ambient temperature, and data indicative of a current date and a current time. The power control module selectively applies power to a heater of a crankcase of the compressor and selectively disables the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time.

摘要： The present invention inhibits suction of dust and moisture into a drive chamber for driving a piston of a fluid pump while reducing drive load through feeding/discharging of fluid to/from the drive chamber. In the interior of a cylinder, a pressure increasing/decreasing chamber is formed between a valve unit on the cylinder head side and the piston. On the opposite side of the pressure increasing/decreasing chamber, the drive chamber is disposed. There are provided a ventilation path for communicating the drive chamber and the outside space, a fluid path connected to the feeding/discharging space of the valve unit, a merging space where the fluid path is merged with the ventilation path midway, and a fluid filter provided in the merging space.

摘要： A reciprocating device which may be operated either as a compressor or an engine. Each cylinder has a reciprocating piston connected to a piston rod. Dual cylinder chambers are located in each cylinder on opposite sides of the piston. The pistons are connected to a scotch yoke which translates the reciprocating motion of the pistons to rotary motion at a shaft in the engine mode. In the compressor mode, the shaft is connected to a power source. The engine components such as the pistons, rods, bushings and cylinder lines may be high quality steel or a ceramic.

摘要： A booster-type gas compressor comprises a compressed-gas flow path, a cylinder, and a piston that moves up and down in the cylinder to further compress a compressed gas fed into the cylinder from the compressed-gas flow path. In a crank case, a crank shaft is rotated with a driving shaft to move the piston up and down. The compressed-gas flow path is connected to the crank case via a bypath conduit to make pressure difference above and under the piston reduced.
