An oil separator for separating oil from a refrigerant gas and oil mixture on the high side of a refrigeration/chiller system comprising, a housing having an upper chamber with an inlet for the refrigerant gas and oil mixture, and having a refrigerant gas outlet therefrom, the outlet conduit being connected to multiple outlets for delivery of refrigerant gas to multiple condenser circuits in the system, and said housing also having a lower chamber with an oil outlet therefrom, and at least one oil filter in said upper chamber for removing oil out of the mixture for transfer to the lower chamber.

Multiple outlet vertical oil separator

An oil level regulator is disclosed for use in a refrigeration system which has an oil reservoir and at least one compressor with a crankcase for containing oil. The regulator has a body with an interior fluid chamber for receiving oil. An inlet communicates with the fluid chamber of the body and is connected by a conduit to the oil reservoir of the system. An outlet communicates from the fluid chamber through a conduit through to the crankcase of the compressor. A level detecting mechanism is disposed within the fluid chamber for detecting an oil level therein. The level detector mechanism includes a solenoid assembly which is actuated by the detector mechanism when the oil level within the chamber is determined to be at or below a predetermined level. A microprocessor is provided on the regulator which communicates with the detector mechanism and the solenoid assembly. The microprocessor includes a delay timer for actuating the switch mechanism after a delay time period has passed from detection of a low oil level in order to provide fluid to the interior chamber. The microprocessor also includes a latching timer for holding the solenoid assembly in a position for feeding oil into the fluid chamber for a latching time period after an oil level is detected which is at or above the first predetermined level.

Electromechanical regulator

A sight glass assembly for visually indicating the presence of moisture, oil or an acid in a refrigerant flow of a refrigeration or air conditioning system and a method of manufacture thereof is disclosed. The sight glass assembly includes an indicator cap attached to an in-line connector body. The indicator cap includes a piece of transparent sight glass. The sight glass is attached to the indicator cap and to a retaining tube that holds an indicator material. In a preferred embodiment, the sight glass is attached to the indicator cap and to the retaining tube by at least partially melting the sight glass so that it bonds with the indicator cap and, when the sight glass is in at least a partially molten condition, pressing the retaining tube into an inside surface of the sight glass to fixedly attach the retaining tube to the sight glass.

Indicator cap and method of manufacture thereof

An oil level regulator is provided for controlling the oil level in the crankcase of one or more refrigeration compressors or the like. The regulator has a closed chamber for containing the oil. An inlet valve assembly extends into the chamber and includes a float-controlled valve for introducing liquid into the chamber as necessary to maintain the oil level in the chamber and compressor crankcases. The inlet valve assembly includes a vertically telescoping piston for adjusting the float valve and the oil level regulator in the regulator chamber. The piston is moveable from outside the chamber in response to rotation of a concentric stem having a bore through which oil flows into the chamber. The float valve includes a lever bracket which extends horizontally across the chamber to contact a top of a float ball. The lever bracket pivots to cause side-to-side motion of a valve needle against a valve seat to control oil flow into the chamber.

Oil level regulator

An oil level regulator is provided for controlling the oil level in the crankcase of one or more refrigeration compressors or the like. The regulator has a closed chamber for containing the oil. A float-controlled switch is operable to actuate a solenoid valve for introducing liquid into the chamber as necessary to maintain the oil level in the chamber and compressor crankcases.

Electromechanical oil level regulator

An improved oil/gas separator having an upright cylindrical housing with a radial oil/gas inlet and a gas outlet pipe arranged within the housing downward and terminating within the housing with an open end. A helical wall is mounted coaxially around the gas outlet pipe and an oil collection zone is arranged below the open end of the gas outlet pipe. A drip ring is mounted at a low end portion of the gas outlet pipe adjacent to the open end to prevent oil from being entrained into the gas proceeding into the open end. A replaceable porous filter can be provided above an exit end of the gas outlet pipe for a last stage of oil removal from the gas flowing through the separator. A baffle is arranged below the porous filter and above the helical wall for collecting oil removed by the porous filter.

Helical oil separator

The present invention provides an improved oil separator in which the oil/refrigerant mixture is caused to flow through two different filter elements. Each of the filter elements is contained in a separate chamber within the separator. A valve assembly is also provided that selectively permits only oil to flow from the first chamber to an oil collection area in the second chamber. The valve assembly regulates the flow of collected oil to the collection area such that the oil/refrigerant mixture cannot escape from the first chamber except by flowing through the filter element of the second chamber. In one embodiment, the valve assembly can include an elongated oil drain extending from a first end adjacent to an oil drain aperture in a dividing wall separating the first and second chambers to a second, open end. A valve seat is formed on the second end of the oil drain. A ball valve element is provided for selective sealing engagement with the valve seat, and the ball valve element is biased toward engagement with the valve seat by a resilient member. In a preferred embodiment, the invention provides a multi-stage device for separting oil from a gas. The device includes a first chamber having an access opening and containing a first filter element. A second chamber is provided adjacent to the first chamber, and contains a second, replaceable filter element. A passage is formed in the first chamber that leads from the second chamber through the access opening in the first chamber, whereby the second, removable filter element can be removed from the second chamber through the access opening via the passage. The second, replaceable filter element may be removed from the separator by means of an elongate handle member having a first end secured to the replaceable filter element, and a second end disposed adjacent to the access opening in the first chamber.

Two-stage helical oil separator

A device for separating oil from a gas is provided which includes a housing forming a peripheral wall with an inlet at a top end of the housing for receiving an oil/gas mixture, a gas outlet formed by a conduit extending through the top end of the housing and an oil outlet at a bottom end of the housing. Within the housing there is a helical wall extending between the gas outlet conduit and the peripheral wall to cause the oil/gas mixture to flow in a largely circumferential path along the peripheral wall. Between the helical wall and the peripheral wall there is provided a mesh screen for collecting and separating the oil from the oil/gas mixture. The collected oil drips from the screen to a baffle with apertures therein which directs the oil therethrough for receipt in an oil collection zone below the baffle. The gas outlet conduit has an opening above the baffle for permitting relatively oil-free gas to exit the oil separator.
