摘要： PURPOSE:To reduce gas flow and prevent an operation space from intrusion of lubricating oil by disposing a fixed orifice on the way of a bypass communicating pipe interconnecting a distance space and buffer space in a heat engine. CONSTITUTION:A heat engine is provided with a power piston 15, a cross head 13 connected and disposed to form a distance space 28 or the like. The distance space 28 is adapted to have averaged pressure higher than that in a buffer space 29. While an oil separator 42 and check valve 43 are disposed on the way of a bypass communicating pipe 41 affording communication between the buffer space 29 and distance space 28, a fixed orifice 45 is interposed. Also, a capillary tube or variable type needle valve or the like may be provided in place of the fixed orifice 45. Thus, an amount of oil grains intruding into the distance space 28 from the buffer space 29 can be reduced by throttling the oil flow on the way of the bypass communicating pipe 41.

摘要： PURPOSE:To reduce abrasion of a seal member and allow oil return from a high pressure side to a low pressure side by fitting an annular seal member to each of a drive shaft and a support shaft via a gap smaller than that between each shaft and a bearing thereof, and preventing movement of the seal members toward an equipment chamber side by means of respective seal retainers. CONSTITUTION:A first seal member 36 is fitted to a drive shaft 32 on an equipment chamber 26 side of a first bearing 33, and movement thereof toward the chamber 26 side is prevented by a first seal member retainer 37. A second seal member 38 is fitted to a support shaft 34 on the equipment chamber 26 side of a second bearing 35, and movement thereof is prevented by a second seal member retainer 39. In this constitution, when the inside of a closed chamber 22 becomes a high pressure space, the second seal member 38 is moved by differential pressure between the high pressure space and a low pressure space in the chamber 26 only in the radial direction to shift an axis so that seizure can be prevented even when the member 38 is brought into contact, with the support shaft 34.

摘要： PURPOSE:To restrain oil-up even during high rotational speed operation by forming a closed space with which the flow rate of lubrication oil scattered from the slide part between a cross head and a cylinder is retarded, together with the upper surface of the cross head and the inner surface of the cylinder. CONSTITUTION:A seal 50 made of sponge and adapted to slide in a cylinder 39 is clamped between an oil scatter preventing plate 24 and a retainer plate 52 and is disposed in the upper section of a cross head 34 which is connected to one end of a connecting rod 33 within a crank casing 31 and which is connected to a piston rod 35. Further a gap between the cross head 34 and the cylinder 39 is blocked. With this arrangement, it is possible to prevent scattered oil from passing between the oil scattering preventing plate 24 and the cylinder 39, and to push back oil stagnated on the upper surface of the cross head 34, into a buffer chamber 29 due to a pressure differential. Accordingly, it is possible to limit the amount of oil going over an oil absorbing member 17 and flowing into a compression chamber 37, to a slight value.

摘要： PURPOSE: To stabilize the output of a Stirling heat engine by providing at its output an electric load for controlling the rotation of this engine to hold its load const. CONSTITUTION: For driving a heat pump with a Stirling engine 1 as a power source, a rotational speed sensor 12 provided on the output shaft of the engine 1 measures the rotational speed variation of the engine 1 due to the variation of an air conditioner load or outside light, a field regulator 13 adjusts the field system of a generator 14 also provided on the output shaft and this generator 14 controls the rotational speed of the engine 1. Thus the electric load compensates the increment/decrement of the heat pump load, thereby always holding the entire load const. to result in a stable heat pump system.

摘要： PURPOSE:To obtain an oil immersion preventing structure with high reliability by providing a pressure control mechanism for holding a pressure in the upper space of a crosshead higher than that in the lower space. CONSTITUTION:The open end 2a of a draft tube 2 to the space 6 inside a crank case is located a position where it is blocked by the crosshead 24 even when the crosshead 24 is located at lower dead point (c) in reciprocation. The open end 2b to the upper space of the crosshead is blocked by the side surface of the crosshead 24 when the crosshead 24 is located in the vicinity of the upper dead point (b), and when the crosshead 24 is located at the lower dead point (c), the open end 2b is located at the position connecting to the groove 1 provided on the crosshead 24. In such a positional relation the open ends 2a and 2b of the draft tube 2 are arranged so that it is possible to usually hold the average pressure in the upper space of the crosshead higher than that of the average pressure in the space 6 inside the crank case.

摘要： PURPOSE:To obtain an output control device compact with a simplified mechanism by performing an output control regulating a mean pressure in acting space of an engine while constituting a pressure regulating compression chamber of a bearing part of an air feed piston rod and a power piston rod. CONSTITUTION:An air feed piston rod 30, which is integrally formed with an air feed piston comprising a large contour bearing part and a small contour rod part, is inserted to be fitted into a power piston 9 integrally having a power piston rod 32 moved reciprocating through a connecting rod by rotating a crankshaft. While providing seals 34, brought into slide contact with the outer surface of the power piston rod 32, respectively in flange-shaped compression chamber walls 35, 35 integrally provided with a crankcase in two upper and bottom predetermined positions, a compression chamber 36 is partitioned between both the compression chamber walls 35, 35. This compression chamber 36 communicates with low temperature side space 5 through a controlling circuit 39 interposing a control valve 40, dividing a reaction chamber 6 into upper and bottom spaces communicating through a bypass circuit 29.
