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 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.

摘要： A valve plate assembly includes an upper valve plate, a lower valve plate, an annular spacer and a center spacer. The annular spacer is located between the upper and lower valve plates and around the outer periphery of the upper and lower valve plates. The center spacer is located at approximately the geometric center of the valve plate assembly to provide additional support for the valve plate assembly.

摘要： There is disclosed herein a lubrication system for a compressor which provides means for separating and flushing foreign particles contained in the lubricant so as to minimize the number of such particles being circulated through the lubrication system thereby reducing the possibility of damaging the bearings. The foreign particles are separated from the main lubricant flowpath by centrifugal forces and are flushed downwardly into collection means in the lower bearing housing and out through a passage provided therein back to the oil sump. An extension of this passage in the lower bearing housing is also adapted to cooperate with a portion of an axial thrust bearing to prevent rotation thereof.
摘要翻译： 这里公开了一种用于压缩机的润滑系统，其提供用于分离和冲洗包含在润滑剂中的异物的装置，以便使通过润滑系统循环的这种颗粒的数量最小化，从而减少损坏轴承的可能性。 外来颗粒通过离心力与主润滑剂流动路径分离，并被向下冲洗到下轴承壳体中的收集装置中，并通过设置在其中的通道返回到油底壳。 该通道在下轴承壳体中的延伸部也适于与轴向止推轴承的一部分配合以防止其旋转。
