摘要： A combustion pressure sensor is formed of a ring-shaped cylindrical body. The combustion pressure sensor detects combustion pressure in a combustion chamber of an engine by being attached to an outer periphery of a tip of a functional component attached to the combustion chamber. The cylindrical body forms sealed space sealed with a ring-shaped diaphragm on one side and with a ring-shaped support member on an opposite side. The sealed space is defined by an external cylindrical member and an internal cylindrical member coaxial with each other. The diaphragm has a ring-shaped pressure receiving part formed on a side near the combustion chamber to receive pressure from outside and a ring-shaped transmitting part formed on a rear surface of the diaphragm. A pressure transmitting member and a pressure detecting element are provided in the sealed space. Tight abutting contact is formed between the transmitting part of the diaphragm and the pressure transmitting member, between the pressure transmitting member and the pressure detecting element, and between the pressure detecting element and the support member.

摘要： A drive torque estimation device secures accuracy of a drive torque of a compressor by accurately grasping a flow rate of refrigerant in a cycle. The pressure difference is detected by a condenser as a resistor for calculating the flow rate. The pressure difference between two portions based on physical quantities relating to refrigerant pressures is detected using first and second sensors arranged at two portions in the cycle. A flow rate is calculated based on the detected pressure difference. The first sensor may be an upstream-side pressure sensor arranged at an inlet of the condenser or at a high-pressure side pipe upstream of the inlet and detects a pressure of the refrigerant flowing therethrough, and the second sensor may be a downstream-side pressure sensor arranged at a gas/liquid mixed phase region of the condenser and detects a pressure of the refrigerant flowing therethrough or may be a temperature sensor.

摘要： An instrumentation rake assembly comprises a rake tower capped at an immersed end and mated to a lead carrier at a base end. The rake tower comprises a curved wall oriented along a longitudinal axis and supporting a plurality of probe holders. The curved wall has an inner surface defining an internal passage for carrying instrumentation from the probe holders to the lead carrier. In another aspect, an instrumentation rake assembly comprises a plurality of rake towers, each having a base end and an immersed end, and each rake tower being coupled at its immersed end to one or more other rake towers.

摘要： A component adapted to transmit a dynamic pressure signal from a high temperature environment to a location where it can be measured without causing significant attenuation of the signal. In particular, the component provides for a dynamic pressure signal transmission in the manner that will not result in the formation of condensation in the measurement system and thus eliminates the need to periodically purge condensate from the system.

摘要： An improved compression tester and novel fittings therefor, the hose of the tester being provided with a nipple concentrically threaded both internally and externally, the internal threads engaging a check valve independent of the mounting of the fittings on the external threads. The two fittings are reversible, both ends of at least one of the fittings being externally threaded for a distance along the length of the fitting, the distance differing for the two ends. The internal threading by which both fittings threadably engage the nipple of the base is along the center portion only of the bore.
