摘要： An apparatus is provided and may include a control valve that moves a pressure-responsive unloader valve between a first position permitting flow through a valve plate and into a compression mechanism and a second position restricting flow through the valve plate and into the compression mechanism. The control valve may include at least one pressure-responsive valve member movable between a first state supplying discharge-pressure gas to the unloader valve to urge the unloader valve into one of the first position and the second position and a second state venting the discharge-pressure gas from the unloader valve to move the unloader valve into the other of the first position and the second position.

摘要： An apparatus is provided and may include a compression mechanism, a valve plate associated with the compression mechanism and having at least one port in fluid communication with the compression mechanism, and a manifold disposed adjacent to the valve plate. A cylinder may be formed in the manifold and a piston may be disposed within the manifold and may be movable relative to the manifold between a first position separated from the valve plate and a second position engaging the valve plate. A valve element may be disposed within the piston and may be movable relative to the piston and the manifold. The valve element may be movable between an open position spaced apart from the valve plate and permitting flow through the port and into the compression mechanism and a closed position engaging the valve plate and restricting flow through the port and into the compression mechanism.

摘要： A hermetic motor-compressor has a motor cover or shroud overlying the end turns of the motor windings. The motor cover is secured to a fastening device in the form of a ring held in place by the stator fastening bolts. A molded plastic holder or retainer for a motor protector is fitted on a lug formed on the ring. The retainer is adapted to hold protectors of different physical configurations. The lug projects upwardly inside the cover and in one embodiment the retainer is trapped between and held in position by the ring and the cover. The protector is of the thermally responsive electrical cutout type and is maintained in closely overlying heat conductive relationship with respect to the end turns of the motor windings by the motor cover. The parts which hold the retainer and the protector in place are movable into their holding positions by the act of moving the cover down into position, in a direction generally parallel to the axis of the motor.

摘要： A heat exchanger (10) disclosed functions as a grate for an enclosed stove and includes a front hearth section (14) of an upwardly opening U-shape including tubing for carrying a fluid to be heated. An open end of the front hearth section allows an associated stove to be stroked through a front door opening thereof as well as through a top opening of the stove. A rear flue section (20) of the heat exchanger includes tubing for carrying fluid to provide preheating thereof by flue gases prior to passage to the hearth section. Inlet and outlet tubes (24, 26) of the heat exchanger respectively supply the fluid to be heated to the flue section and receive the heated fluid from the hearth section. A central connector tube (28) preferably extends between the flue and hearth sections with grate tubes (30) of the hearth section extending from the connector tube to define the U-shape thereof and with a pair of the outlet tubes communicated with upper ends of the grate tubes. U-shaped tubes (32) of the flue section open sideways in opposite directions and have upper ends communicated with the inlet tube and lower ends communicated with the connector tube that feeds the hearth section.
