A dryer for a compressed gas provided with a vessel with a drying agent and a drying zone and a regeneration zone; at least one intermediate zone that, viewed in the direction of rotation of the drum, is situated between the regeneration zone and the drying zone and which is provided with a separate inlet and an outlet that is shared with or connected to the outlet of the regeneration zone; a tap-off pipe that branches off from the outlet of the drying zone and connects to the aforementioned separate inlet of the intermediate zone; means for effectuating an intermediate flow from the drying zone, whereby the dryer is configured such that the entire flow of gas to be dried supplied to the dryer is first guided through the regeneration zone, wherein the aforementioned means are only formed by one or more blowers in the aforementioned tap-off pipe.

The present invention relates to a condensate drain valve, which is connected to a condensate discharge pipe of an air compression equipment, for discharging the condensate generated inside the air compression equipment together with compressed air to the outside, which comprises: a main body; an opening and closing member, and a communication path formed therein for communicating the inlet hole and the discharge hole. According to the present invention, the automatic drain valve for condensed water capable of continuously and automatically discharging the condensed water generated in the air compression device even during the operation of the air compression device can be formed in a compact structure, thereby facilitating the manufacture of the device and remarkably reducing the manufacturing costs.

A vehicle air management system is provided. The vehicle air management system comprises an air tank and a boost air tank. Based on a signal indicative of an air consumption level of at least one air consumer, a control unit is configured to control the vehicle air management system to deliver pressurized air from the boost air tank to be supplied to an air compressor.

An oil catch apparatus is provided. The oil catch apparatus is capable of efficiently extracting oil from air flowing through the oil catch apparatus while being of compact size. A filter of the oil catch apparatus includes a cylindrically wound main filter unit and a keep member for keeping both ends of the main filter unit. Air flowing into the main filter unit is cleared of impurities upon passing through the main filter unit, and exits out of the main filter unit.

A connector (24) and method of connecting a compressor assembly (10) that increases the pressure of a fluid are described. The compressor assembly (10) includes cylinders (12a,b), crank shaft housings (18a,b), and a motor housing (22). The connector (24) is disposed between the cylinders (12a,b) and the crank shaft housing (18a,b) and configured to engage the cylinders (12a,b) such that vibration during operation of the compressor assembly is reduced through the placement of the connector (24) corresponding to a center of gravity of the compressor assembly (10). The connector may also be used by the compressor assembly as a heat sink, inlet, mount, filter, and/or to provide other functions that improve the operation of compressor assembly.
