Title: Reciprocating compressor
Inventor: KIMURA KAZUYA
IPC: F04B39/10
Filed: 1993-03-15
Abstract: PURPOSE:To improve the volumetric efficiency of a reciprocating compressor for a vehicle air conditioner by forcibly and divertedly guiding part of the refrigerant gas tending to flow toward a bore having a large stroke change with a guide plate in the intake groove of a rotary valve, and blowing it into a bore at the suction final stage via the inertial force of the flowing gas. CONSTITUTION:When a drive shaft is rotated, a rotor and a swash plate are rotated, a rocking plate is rocked, pistons are reciprocated, and a rotary valve 30 is synchronously rotated. When one piston starts a suction stroke, the advance side wall face 33b of an intake groove 33 in the rotating direction shown by an arrow is communicated with the continuity path 22 of a closed bore, e.g., a bore 1F, and the refrigerant gas is sucked into the bore 1F. A trend of alienation occurs on a bore 1D at the suction final stage by the gas flow sucked by a bore 1E having a large suction capability, however part of this gas is forcibly guided to a narrow space S by the function of a guide plate 34 and sucked into the bore 1D.

Abstract: PURPOSE:To obtain a low-pass filter whose cut-off frequency is varied with an external control voltage by controlling a differential input fed to each base of a 1st and 2nd transistor (TR) constituting a differential amplifier so as to very the cut-off frequency. CONSTITUTION:The cut-off frequency variable low-pass filter consists of NPN TRs Q1-Q4, resistors R1-R4 and a capacitor C. Then an input terminall is connected to a base of the TR Q4 via an input resistor R2 and the resistor R4 is connected between the emitter of the TR Q4 and a ground terminal 4. Through the constitution above, the current flowing to the resistor R1 is multiplied by alpha (0<=alpha<=1) by a voltage  V impressed to the bases of the TRs Q1, Q2. As a result, the relation of equation is obtained, where Vi is a voltage at an input terminal 1 and Vo is a base voltage of the TR Q4.
