摘要： PROBLEM TO BE SOLVED: To increase an energy efficiency by reducing a flow path resistance at the time of delivery while preventing a back flow from a delivery space side to a outer line side compressive space in scroll fluid machinery. SOLUTION: This scroll fluid machinery comprises a delivery port 50 delivering compressed working fluid from a compression space formed of a fixed scroll 2 and a swing scroll 3 to a delivery space 16 and a delivery valve 19 opening the delivery port 50 when a pressure on the compression space side is larger than that on the delivery space side. The delivery port 50 is formed so as to communicate with an outer line side compression space 4b2 before an innermost peripheral compression space 4c communicates with an outer line side compression space 4b2 on the outside of the innermost peripheral compression space through the side faces of both laps.

摘要： PROBLEM TO BE SOLVED: To provide a variable phase device using fluctuating torque of a camshaft as driving force capable of attaining both of an enhanced responsiveness and convergence to a target phase angle, and functioning even during high speed rotation of an engine. SOLUTION: The variable phase device has structure of opening and closing a conduction path comprising a conduction channel 5c between an advance chamber and a delay chamber filled with incompressible oil in which the capacities increase/decrease interlocked with phase conversion, and a conduction hole 12a of a conduction channel opening/closing member 12 synchronized with fluctuating torque acting on the camshaft (base 5 integral therewith), and selectively taking out only one code part of the fluctuating torque as driving force. Opening and closing of the conduction channel 5c is synchronized with a rotational angle of the camshaft (base 5) and is operated by the conduction channel opening/closing member 12 to open and close the conducting channel 5c without delay, thereby securing responsiveness during a high speed operation. Further, when the speed of the phase conversion is changed by an external command, by allowing to change the overlapping degree of conduction between the conduction hole 12a of the conduction channel opening/closing member 12 and the conduction channel 5c, convergence of the variable phase device is improved.

摘要： PROBLEM TO BE SOLVED: To improve fuel consumption at the time of idling and to increase torque at the time of driving at a high speed by automatically returning the lock position of a variable valve timing mechanism to an intermediate position within a control range immediately before an engine is started. SOLUTION: In this phase variable device for controlling a phase angel being a relative position in rotational directions of a first rotary member 10 and a second rotary member 11, a power transmission mechanism which can select from among a first condition to allow the relative rotations of both the rotary members only in one direction, a second condition to allow them only in a reverse direction, and a third condition (lock condition) not to allow them in both the directions is arranged between both the rotary members. Respective conditions are changeable by a positional relationship between the relative rotational directions of the first and second rotary members, and automatic return from the first or second condition to the third condition (lock condition) can be performed based on a fluctuating torque in a direction opposite to one direction acting on the second rotary member 11 immediately before the engine is started.

摘要： PROBLEM TO BE SOLVED: To reliably and accurately convert a phase between a crankshaft and a camshaft by utilizing fluctuating torque acting on the camshaft as driving force. SOLUTION: With respect to a phase-angle control member 16 in which circumferential rotation is restrained, a vane 5 formed integrally with the camshaft is rotated together with a body 2 driven rotatively by the crankshaft. When the fluctuating torque acting on the camshaft has peaked, a communication hole 12c of a phase-angle detector 12 communicating with an advance-angle hydraulic-oil sump 8 and the communication hole 12d of the phase-angle detector 12 communicating with a retard-angle hydraulic-oil sump 9 come in agreement, in response to the direction of the fluctuating torque being at its peak, with either one of an advance-angle communication groove 16a and an retard-angle communication groove 16b respectively of a phase-angle control member 16 to allow the advance-angle hydraulic-oil sump 8 to communicate with the retard-angle hydraulic-oil sump 9. Thus, the phase of the vane 5 is converted with respect to the body 2 in the direction corresponding to the direction of the fluctuating torque being at its peak. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To simplify a valve mechanism in a reciprocating type positive displacement machine, to suppress generation of a sliding load between a piston and a cylinder, and to further prevent reliability of a sliding unit due to a liquid refrigerant in an expansion unit built in a refrigerating cycle.
SOLUTION: The positive displacement machine includes a reciprocating member which performs a shaking motion in association with a reciprocating motion, and switches a conduction between an operating chamber and an intake pressure space or discharge pressure space by utilizing the shaking motion. Further, a symmetry is incorporated in its intake/discharge route, and sliding loads due to the pressure operating on the side face of the piston are canceled each other. The generation of the sliding load is suppressed to remarkably alleviate the sliding condition, and even when lubricating oil is insufficient due to the liquid refrigerant, reliability is assured.

摘要： PROBLEM TO BE SOLVED: To provide a reliable and simply constituted displacement-type machine in which over-expansion can be suppressed even through an expansion volume ratio is very large, wasteful power consumption of an expansion device is prevented, reduction in recovered power of the expansion device is suppressed, and a high efficiency is attained reliably in the condition of a wide range of operation pressure.
SOLUTION: In the displacement-type machine, an operation chamber 7 of a part of the expansion device is allowed to communicate with a discharge side (a discharge pressure space 18 and a discharge pipe 11) through a differential pressure actuated valve 15 which allows only a flow of a working fluid from the discharge side into the direction of the operation chamber. Thus, in the case when the pressure of the operation chamber is reduced lower than the pressure of the discharge side due to expansion of the working fluid, the working fluid on the discharge side is supplied to the operation chamber through the differential pressure actuated valve.
