Abstract
A separator tank assembly comprising a cast hollow tank and a cast lid. The cast hollow tank has a closed end and an open end having a first opening and a second opening. The cast lid has a first passage configured for fluid communication with the tank first opening and a second passage configured for sealed fluid communication with the second opening. The first passage is formed with an integral port configured to receive a pressure control valve and the second passage is formed with an integral port configured to receive an oil filter and wherein the tank is configured such that air having undergone primary separation flows through the first opening and oil within the tank flows through the second opening.
Claims39
A separator tank assembly comprising:
- a cast hollow tank having a closed end and an open end with a separator chamber therebetween;
- a cast lid substantially closing the tank open end;
- a first integral fluid passage integrally cast in the cast hollow tank and cast lid and extending from the separator chamber to at least one external port, wherein the first integral fluid passage is a compressed air passage and wherein at least a first integral port is formed along the first integral fluid passage between the separator chamber and the external port;
- wherein the first integral port is configured to receive a separator element;
- and
- wherein the first integral port has a first integral separator passage extending from the first integral fluid passage to the separator element and a second integral separator passage extending from the separator element to the first integral fluid passage such that compressed air travels from the separator chamber, through the first integral fluid passage, through the first separator passage, through the separator element, through the second separator passage and through the first integral fluid passage to the external port.

- a cast hollow tank having a closed end and an open end with a separator chamber therebetween;
- a cast lid substantially closing the tank open end;
- a first integral fluid passage integrally cast in the cast hollow tank and cast lid and extending from the separator chamber to a first external port configured for providing compressed air to an external component;
- a second integral fluid passage integrally cast in the cast hollow tank and cast lid and extending from the separator chamber to a second external port configured for returning cleaned lubricant to an associated compressor assembly;
- wherein at least a first integral port is formed along the first integral fluid passage between the separator chamber and the first external port;
- wherein the first integral port is configured to receive a separator element;
- and
- wherein the first integral port has a first integral separator passage extending from the first integral fluid passage to the separator element and a second integral separator passage extending from the separator element to the first integral fluid passage such that compressed air travels from the separator chamber, through the first integral fluid passage, through the first separator passage, through the separator element, through the second separator passage and through the first integral fluid passage to the first external port.

- and
- a first integral fluid passage integrally cast in the cast hollow tank and cast lid and extending from the separator chamber to at least one external port;
- wherein at least a first integral port is formed along the first integral fluid passage between the separator chamber and the external port,
- wherein the first integral port is configured to receive a minimum pressure check valve which prevents passage of the compressed air through the first integral fluid passage to the external port unless an air pressure within the separator chamber is above a predetermined level;
- and
- wherein a housing for the minimum pressure check valve is integrally cast into the cast tank and cast lid.
