Cylinder Head Assembly For Reciprocating Compressor

Номер: US20170122302A1
Автор: Ernest R. BERGMAN, Brian G. SCHROEDER, Michael R. SCHULTZ NAVARA, Adam Michael BLAKE, BERGMAN ERNEST R, SCHROEDER BRIAN G, SCHULTZ NAVARA MICHAEL R, BLAKE ADAM MICHAEL, BERGMAN Ernest R., SCHROEDER Brian G., SCHULTZ NAVARA Michael R., BLAKE Adam Michael

A compressor may include a housing, a piston, and a cylinder head assembly. The housing defines a cylinder and a first valve seat defining a recess. The piston is movable within the cylinder to define a compression chamber. The cylinder head assembly is mounted on the housing and includes a valve plate, a suction valve, a discharge valve and a head cover. The valve plate may be mounted to the mounting surface and may include a suction plenum, a suction passage providing fluid communication between the suction plenum and the cylinder, and a discharge passage. The suction valve can seat on the first valve seat to allow fluid flow through the suction passage. The head cover may include a discharge chamber and an integrally formed guide post extending into the discharge chamber. The guide post may include a pocket that receives a discharge valve stem for reciprocation therein.

A compressor assembly is provided and may include a compression cylinder and a compression piston disposed within the compression cylinder that compresses a vapor disposed within the compression cylinder from a suction pressure to a discharge pressure. The compressor assembly may additionally include a crankshaft that cycles the compression piston within the compression cylinder and an injection port in fluid communication with the compression cylinder that selectively communicates intermediate-pressure vapor at a pressure between the suction pressure vapor and the discharge pressure vapor to the compression cylinder. The injection port may communicate the intermediate-pressure vapor to the compression cylinder when the compression piston exposes the injection port and may be prevented from communicating the intermediate-pressure vapor to the compression cylinder when the compression piston blocks the injection port. 1. A compressor assembly comprising:a compression cylinder;a compression piston disposed within said compression cylinder and operable to compress a vapor disposed within said compression cylinder from a suction pressure to a discharge pressure;a crankshaft operable to cycle said compression piston within said compression cylinder; andan injection port in fluid communication with said compression cylinder and operable to selectively communicate intermediate-pressure vapor at a pressure between said suction pressure vapor and said discharge pressure vapor to said compression cylinder, said injection port communicating said intermediate-pressure vapor to said compression cylinder when said compression piston exposes said injection port and prevented from communicating said intermediate-pressure vapor to said compression cylinder when said compression piston blocks said injection port.2. The compressor assembly of claim 1 , wherein said compression piston is movable within said compression cylinder between a top dead center (TDC) position and a bottom dead ...

Cylinder Head Assembly For Reciprocating Compressor

Номер: US20190376501A1

Принадлежит: Emerson Climate Technologies Inc

A compressor may include a housing, a piston, a valve plate, a discharge valve and a head cover. The housing defines a cylinder. The piston is disposed within the housing and is movable within the cylinder. The valve plate is mounted to the housing and may include a discharge passage extending through the valve plate and defined by a discharge valve seat. The discharge valve is movable between a first position in which the discharge valve is seated on the discharge valve seat to restrict fluid flow through the discharge passage and a second position in which the discharge valve is spaced apart from the discharge valve seat to allow fluid flow through the discharge passage. The head cover may include a guide post including a pocket that receives a valve stem of the discharge valve.

A compressor may include a compression cylinder, a compression piston, a crankshaft, an injection bore, a position sensor, and a valve assembly. The compression piston is disposed within the compression cylinder and is operable to compress a vapor disposed within the compression cylinder from a suction pressure to a discharge pressure. The crankshaft is operable to cycle the compression piston within the compression cylinder. The injection bore may be in fluid communication with the compression cylinder and may be operable to selectively communicate intermediate-pressure vapor at a pressure between the suction pressure and said discharge pressure to the compression cylinder. The position sensor may measure a rotational position of the crankshaft. The valve assembly may be associated with the injection bore. The valve assembly may be operable to control passage of fluid from the injection bore into the compression cylinder in response to data provided by the position sensor.
