Abstract:
It is intended to provide a vacuum pump so that without upsizing the vacuum pump, noise and vibration are reduced, heat dissipation property is secured, and the casing is downsized. Therefore, at least one turning part is provided in an exhausting path formed in a casing body. The casing body is formed of a material whose thermal conductivity is higher than that of a rotor and vanes, and a cylinder part where the vanes slide is press fitted in the casing body.
Abstract:
A brake system includes a service brake and a parking brake that brake a vehicle including a lift axle capable of ascending and descending. The brake system further includes a brake blocker device and a controller that controls the brake blocker device. The brake blocker device blocks at least one of supply of compressed air to the service brake and supply of compressed air to the parking brake. The service brake and the parking brake act on the lift axle. The controller actuates the brake blocker device when the lift axle is at a lifted position.
Abstract:
A compressed air drying device that dries compressed air discharged from a compressor includes a dryer and a controller. The dryer includes a drying container, which is filled with a desiccant, and a discharge valve arranged in a discharge port that discharges drainage produced by regeneration of the desiccant. The controller obtains an ambient temperature and controls opening and closing of the discharge valve. When the ambient temperature is a temperature at which freezing occurs, the controller moves the compressed air, which is discharged from the compressor and heated, into the dryer and restricts opening of the discharge valve.
Abstract:
A compressed air drying device includes a support base including an inlet of compressed air from a compressor, an outlet of the compressed air, and a discharge port of oil and water. The discharge port includes a drain valve device and a drying container. The container is filled with desiccant and is installed in the support base. In a loading operation, the compressed air drying device causes the desiccant to dry the compressed air introduced through the inlet and discharges the dried compressed air through the outlet. In an unloading operation, the compressed air drying device causes the compressed air to pass through the container to discharge oil and water from the discharge port. A glass fiber filter is provided at one or more of a position upstream of the desiccant and a position downstream of the desiccant in a flow of the compressed air during the loading operation.
Abstract:
An air dryer includes a supporting base, a drying agent container, and an outer cover. The supporting base includes an inlet for receiving compressed air to be subject to a drying process and an outlet for delivering the processed compressed air that has undergone the drying process. The drying agent container is a container supported on the supporting base, contains a drying agent in the interior, and enables the drying process to be performed by passing the compressed air from the inlet through the drying agent. The outer cover surrounds the outer side of the drying agent container on the supporting base and defines a chamber for storing the compressed air between itself and the drying agent container. The supporting base includes first and second mounting surfaces, which are oriented in different directions, and a plurality of inlets, which are oriented in different directions and receive the compressed air.
Abstract:
A compressed air drier includes a support base, a desiccant cartridge coupled to the support base, and a case that covers the cartridge and is coupled to the support base. The support base includes an inlet for compressed air from a compressor, an outlet for the compressed air, and a discharge port for oil and water including a drain valve device. An electrically charged oil adsorbent is accommodated between the cartridge and the case. The cartridge is filled with a desiccant. The compressed air drier dries the compressed air entering the inlet with the desiccant during a loading operation, collects the dried compressed air in the case, and discharges the dried compressed air from the outlet. The compressed air drier passes the compressed air in the case through the cartridge during an unloading operation to discharge oil and water from the discharge port.

Abstract:
An air drier includes an inlet, an outlet, and a collected liquid discharge port. Compressed air flows in the inlet. Dry compressed air is discharged through the outlet. Purge air containing oil and water is discharged through a collected liquid discharge port. The air drier further includes a drying container that is filled with desiccant, and a case that covers the drying container. The air drier is provided with, downstream of the collected liquid discharge port, a separation portion that separates clean air from oil and water in the purge air, a clean air outlet through which the clean air is discharged, and a collected liquid retaining portion in which collected liquid is retained. The collected liquid is separated oil and water.
Abstract:
An oil separator is provided with a casing having an inlet for air and an outlet for air, an expansion chamber for expanding air introduced therein through the inlet, an accommodation member communicating with the expansion chamber in the vertical direction, a collected liquid storage portion provided below the accommodation member, and a connecting hose having an oil separator connection end for being connected to the inlet and an air dryer connection end for being connected to an air dryer. The connecting hose is configured such that the oil separator connection end is located higher than the air dryer connection end.
Abstract:
An oil separator causes air containing oil to strike an impingement member to separate the oil from the air and recover the oil. The oil separator includes a body having an inlet for introducing air and an outlet for discharging air. The oil separator further includes a cartridge that is assembled to the body and accommodates the impingement member. The oil separator further includes a drain bowl for storing the separated oil. The oil separator further includes an assembling structure. The body and the cartridge are assembled through one or two actions by using the assembling structure.
